These amplifiers fea-ture also large output voltage swing and high out-put current capability to drive standard 150Ωloads.Running at single or dual supply voltage from 4.5V to 12V, these amplifiers are tested at 5V(±2.5V)and 10V(±5V) supplies.The TSH81 also features a Standby mode, which allows the operational amplifier to be put into a standby mode with low power consumption and high output impedance.The function allows power saving or signals switching/multiplexing for high speed applications and video applications.For board space and weight saving, TSH8x series is proposed in SOT23-5, TSSOP8 and SO8 pack-ages.APPLICATIONs Video Buffers s A/D Converters Driver s Hi-Fi ApplicationsPIN CONNECTIONS (top view)D SO8(Plastic Micro package)L SOT23-5(Plastic Micro package)P TSSOP8(Plastic Micro package)TSH80-TSH81-TSH82WIDE BAND, RAIL to RAIL OPERATIONAL AMPLIFIERWITH STANDBY FUNCTIONFebruary 2003TSH80-TSH81-TSH822/18ABSOLUTE MAXIMUM RATINGSOPERATING CONDITIONSORDER CODESI = Temperature rangeD = Small Outline Package (SO) -

The power supply capacitors must be incorporated for both the negative and the positive pins.- Proper termination of all inputs and outputs must be in accordance with output termination resistors;then the amplifier load will be only resistive and the stability of the amplifier will be improved. All leads must be wide and as short as possible especially for op amp inputs and outputs in order to decrease parasitic capacitance and inductance.- For lower gain application, attention should be paid not to use large feedback resistance (>1k Ω)to reduce time constant with parasitic capacitanc-es.- Choose component sizes as small as possible (SMD).- Finally, on output, the load capacitance must be negligible to maintain good stability. You can put a serial resistance the closest to the output pin to minimize its influence. CCIR330 video lineMaximum input level:The input level must not exceed the following val-ues:u negative peak: must be greater than-Vcc+400mV.u positive peak value: must be lower than+Vcc-400mV.The electrical characteristics show the influence of the load on this parameter.Video capabilities:To characterize the differential phase and differ-ential gain a CCIR330 video line is used.The video line contains 5 (flat) levels of luma on which is superimposed chroma signal. (the first level contains no luma). The luma gives various amplitudes which define the saturation of the sig-nal. The chrominance gives various phases which define the colour of the signal.Differential phase (respectively differential gain)distortion is present if a signal chrominance phase (gain) is affected by luminance level. They repre-sent the ability to uniformly process the high fre-quency information at all luminance levels.When differential gain is present, colour saturation is not correctly reproduced.The input generator is the Rohde & Schwarz CCVS. The output measurement is done by the Rohde and Schwarz VSA.Measurement on Rohde and Schwarz VSA.TSH80-TSH81-TSH8215/18Video Results:Precautions on asymmetrical supply operation:The TSH8X can be used either with a dual or a single supply. If a single supply is used, the inputs are biased to the mid-supply voltage (+Vcc/2).This bias network must be carefully designed, in order to reject any noise present on the supply rail.As the bias current is 15uA, you must carefully choose the resistance R1 not to introduce an off-set mismatch at the amplifier inputs.R1=10k Ω will be convenient. C1, C2, C3 are by-pass capacitors from perturbation on Vcc as well as for the input and output signals. We choose C1=100nF and C2=C3=100uF.R2, R3 are such that the current through them must be superior to 100 times the bias current. So,we take R2=R3=4.7k Ω.Cin, as Cout are chosen to filter the DC signal by the low pass filters (R1,Cin) and (Rout, Cout). By taking R1=10k Ω, RL=150Ω, and Cin=2uF,Cout=220uF we provide a cutoff frequency below 10Hz.Use of the TSH8X in gain=-1 configuration:Some precautions have to be added, specially for low power supply application.A feedback capacitance Cf should be added for better stability. The table summarizes the impact of the capacitance Cf on the phase margin of the circuit.Parameter Value (Vcc=±2.5V)Value (Vcc=±5V)Unit Lum NL 0.10.3%Lum NL Step 1100100%Lum NL Step 210099.9%Lum NL Step 399.999.8%Lum NL Step 499.999.9%Lum NL Step 599.999.7%Diff Gain pos 00%Diff Gain neg -0.7-0.6%Diff Gain pp 0.70.6%Diff Gain Step1-0.5-0.3%Diff Gain Step2-0.7-0.6%Diff Gain Step3-0.3-0.5%Diff Gain Step4-0.1-0.3%Diff Gain Step5-0.4-0.5%Diff Phase pos 00.1deg Diff Phase neg -0.2-0.4deg Diff Phase pp 0.20.5deg Diff Phase Step1-0.2-0.4deg Diff Phase Step2-0.1-0.4deg Diff Phase Step3-0.1-0.3deg Diff Phase Step400.1deg Diff Phase Step5-0.2-0.1degTSH80-TSH81-TSH8216/18Example of a video application:This example shows a possible application of the TSH8X circuit. Here, you can multiplex the channels for the different standard PAL, NTSC as you filter for the different bands; the video signal can be filtered with two different cutoff frequencies, corresponding to a PAL encoded signal (LPF1) or a NTSC signal (LPF2).You can multiplex input signals, as the outputs are in high impedance state in standby mode. This enables you, to use a PAL filter as the Standby mode is active and to use the NTSC filter otherwise.The video application requires 1Vpeak at input and output. Calculation of components:A decoupling capacitor is provided to cutoff the frequencies below 10Hz according I bias. Hence Ce=10uF, with Rb1=10k Ω. At the output, Cout=220uF.The AOP1 is in 6dB configuration for the adaptation bridge. R1=R2=1k Ω,V1=2Vpk, V2=1VpkFor the PAL communication, we need a low pass filtering. The load resistance R4 is function of the output resistance of the filter.V3=V2/A1 where A1 is the attenuation factor of the filter LPF1.To compensate the filter insertion loss, we add an additional factor to the gain of the 2nd amplifier AOP2.For example, for an attenuation of 3dB, we choose R5=300Ω and R6=1k Ω. We have V4=2Vpk and Vout=1Vpk.The calculation of the parameters R7, C7, R8, C8, R9, R10 will be exactly the same.Parameter Cf (pF)Vcc=±1.5VVcc=±2.5VVcc=±5V Unit Phase Margin0284356deg f-3dB 4039.338.3MHz Phase Margin5.6304356deg f-3dB 4039.338.3MHz Phase Margin22375267deg f-3dB 373432MHz Phase Margin33486578deg f-3dB33.730.727.6MHz17/18PACKAGE MECHANICAL DATA8 PINS - PLASTIC MICROPACKAGE (SO)PACKAGE MECHANICAL DATA8 PINS - THIN SHRINK SMALL OUTLINE PACKAGE (TSSOP)limeters Inches Min.Typ.Max.Min.Typ.Max.A 1.750.069a10.10.250.0040.010a2 1.650.065a30.650.850.0260.033b 0.350.480.0140.019b10.190.250.0070.010C 0.250.50.0100.020c145° (typ.)D 4.8 5.00.1890.197E 5.86.20.2280.244e 1.270.050e3 3.810.150F 3.8 4.00.1500.157L 0.41.270.0160.050M 0.60.024S8° (max.)limeters Inches Min.Typ.Max.Min.Typ.Max.A 1.200.05A10.050.150.010.006A20.80 1.00 1.050.0310.0390.041b 0.190.300.0070.15c 0.090.200.0030.012D 2.90 3.003.100.1140.1180.122E 6.400.252E14.30 4.40 4.500.1690.1730.177e 0.650.025k 0°8°0°8°l0.500.600.750.090.02360.03018/18PACKAGE MECHANICAL DATA 5 PINS - TINY PACKAGE (SOT23)limetersInches Min.Typ.Max.Min.Typ.Max.A 0.90 1.20 1.450.0350.0470.057A100.150.006A20.90 1.05 1.300.0350.0410.051B 0.350.400.500.0140.0160.020C 0.090.150.200.0040.0060.008D 2.802.903.000.1100.1140.118D1 1.900.075e 0.950.037E 2.60 2.80 3.000.1020.1100.0118F 1.50 1.60 1.750.0590.0630.069L 0.100.50.600.0040.0140.024K0d 10d 0d10dInformation furnished is believed to be accurate and reliable.
