device must be derated based on a125 C maximum junction temperature and a thermal resistance of92 C W which applies for the device soldered in a printed circuit board operating in a still air ambient Thermal resistance for the S O package is131 C WNote2 The output current sink capability can be increased for large signal conditions by overdriving the inverting input This is shown in the section on Typical CharacteristicsNote3 This spec indicates the current gain of the current mirror which is used as the non-inverting inputNote4 Input V BE match between the non-inverting and the inverting inputs occurs for a mirror current(non-inverting input current)of approximately10m A This is therefore a typical design center for many of the application circuitsNote5 Clamp transistors are included on the IC to prevent the input voltages from swinging below ground more than approximately b0 3V DC The negative input currents which may result from large signal overdrive with capacitance input coupling need to be externally limited to values of approximately1mA Negative input currents in excess of4mA will cause the output voltage to drop to a low voltage This maximum current applies to any one of the input terminals If more than one of the input terminals are simultaneously driven negative smaller maximum currents are allowed Common-mode current biasing can be used to prevent negative input voltages see for example the‘‘Differentiator Circuit’’in the applications sectionNote6 These specs apply for b40 C s T A s a85 C unless otherwise statedNote7 Human body model 1 5k X in series with100pFApplication HintsWhen driving either input from a low-impedance source alimiting resistor should be placed in series with the inputlead to limit the peak input current Currents as large as20mA will not damage the device but the current mirror onthe non-inverting input will saturate and cause a loss of mir-ror gain at mA current levels especially at high operatingtemperaturesPrecautions should be taken to insure that the power supplyfor the integrated circuit never becomes reversed in polarityor that the unit is not inadvertently installed backwards in atest socket as an unlimited current surge through the result-ing forward diode within the IC could cause fusing of theinternal conductors and result in a destroyed unitOutput short circuits either to ground or to the positive pow-er supply should be of short time duration Units can bedestroyed not as a result of the short circuit current causingmetal fusing but rather due to the large increase in IC chipdissipation which will cause eventual failure due to exces-sive junction temperatures For example when operatingfrom a well-regulated a5V DC power supply at T A e25 C with a100k X shunt-feedback resistor(from the output tothe inverting input)a short directly to the power supply willnot cause catastrophic failure but the current magnitude willbe approximately50mA and the junction temperature willbe above T J max Larger feedback resistors will reduce thecurrent 11M X provides approximately30mA an open cir-cuit provides1 3mA and a direct connection from the out-put to the non-inverting input will result in catastrophic fail-ure when the output is shorted to V a as this then places thebase-emitter junction of the input transistor directly acrossthe power supply Short-circuits to ground will have magni-tudes of approximately30mA and will not cause cata-strophic failure at T A e25 CUnintentional signal coupling from the output to the non-in-verting input can cause oscillations This is likely only in breadboard hook-ups with long component leads and can be prevented by a more careful lead dress or by locating the non-inverting input biasing resistor close to the IC A quick check of this condition is to bypass the non-inverting input to ground with a capacitor High impedance biasing resis-tors used in the non-inverting input circuit make this input lead highly susceptible to unintentional AC signal pickupOperation of this amplifier can be best understood by notic-ing that input currents are differenced at the inverting-input terminal and this difference current then flows through the external feedback resistor to produce the output voltage Common-mode current biasing is generally useful to allow operating with signal levels near ground or even negative as this maintains the inputs biased at a V BE Internal clamp transistors(see note5)catch-negative input voltages at ap-proximately b0 3V DC but the magnitude of current flow has to be limited by the external input network For operation at high temperature this limit should be approximately100m A This new‘‘Norton’’current-differencing amplifier can be used in most of the applications of a standard IC op amp Performance as a DC amplifier using only a single supply is not as precise as a standard IC op amp operating with split supplies but is adequate in many less critical applications New functions are made possible with this amplifier which are useful in single power supply systems For example biasing can be designed separately from the AC gain as was shown in the‘‘inverting amplifier ’’the‘‘difference integra-tor’’allows controlling the charging and the discharging of the integrating capacitor with positive voltages and the‘‘fre-quency doubling tachometer’’provides a simple circuit which reduces the ripple voltage on a tachometer output DC voltage3Typical Performance CharacteristicsOpen Loop Gain Voltage Gain Voltage GainLarge Signal
