As a minimum, each device contains the integrator, zero crossing comparator and processor interface logic. The TC500 is the base (16-bit max) device and requires both positive and negative power supplies. The TC500A is identical to the TC500 with the exception that it has improved linearity, allowing it to operate to a maximum resolution of 17 bits. The TC510 adds an on-board negative power supply converter for single-supply operation. The TC514 adds both a negative power supply converter and a 4-input differential analog multiplexer.Each device has the same processor control interface consisting of 3 wires: control inputs (A and B) and zero-crossing comparator output (CMPTR). The processor manipulates A, B to sequence the TC5XX through four phases of conversion: auto-zero, integrate, de-integrate and integrator zero. During the auto-zero phase, offset voltages in the TC5XX are corrected by a closed loop feedback mechanism. The input voltage is applied to the integrator during the integrate phase. This causes an integrator output dv/dt directly proportional to the magnitude of the input voltage. The higher the input voltage, the greater the magnitude of the voltage stored on the integrator during this phase. At the start of the de-integrate phase, an external voltage reference is applied to the integrator and, at the same time, the external host processor starts its on-board timer. The processor maintains this state until a transition occurs on the CMPTR output, at which time the processor halts its timer. The resulting timer count is the converted analog data. Integrator zero (the final phase of conversion) removes any residue remaining in the integrator in preparation for the next conversion. The TC500/A/510/514 offer high resolution (up to 17bits), superior 50/60Hz noise rejection, low-power operation, minimum I/O connections, low input bias currents and lower cost compared to other converter technologies having similar conversion speeds.Precision Analog Front Ends with Dual Slope ADC© 2008 Microchip Technology Inc.DS21428E-page 1TC500/A/510/514DS21428E-page 2© 2008 Microchip Technology Inc.Package TypesTypical Application12341615141356712111098CMPTR OUTADGND BV DD V IN +V IN –V REF +BUF V SS C INT ACOM V REF −C REF +C REF –C AZ TC500/TC500A 16-Pin PDIP/SOIC/CERDIPV OUT –1234201918CAP–56781723222191011122425262728DGND A B C REF –C INT C AZ BUF ACOM CH4–CH3–CH2–TC514C REF +V REF –V REF + V DD OSC CMPTR OUTCAP+ 16151314CH1–N/CCH1+CH2+CH3+CH4+A0A128-Pin PDIP/SOIC24-Pin PDIP/SOIC123416151456781319181791011122021222324TC510CAP–DGND A B V DD OSC CMPTR OUT V IN +V IN –N/C N/CCAP+ C REF –C INT C AZ BUF ACOM N/C N/C N/C V OUT –C REF +V REF –V REF +Level Shift Control Logic Analog Switch Control SignalsACOMV REF +BUFC AZBuffer Integrator SW R SW IZ CMPTR 1CMPTR 2CMPTROutputDGNDControl LogicSW 1TC500TC500A TC510TC514C REFC REF +SW RC REF -C AZ R INT C INTC INTSW RI -SW RI -SW RI +SW RI -SW ZSW ISW ZV SS OSC+++Phase Decoding LogicPolarity DetectionDC-TO-DC Converter (TC510 & TC514)-+A B0 0 Zero Integrator Output 0 1 Auto-Zero 1 0 Signal Integrate 1 1 De-integrateV REF -V OUT -C OUT -1.0μF1.0μFV SS SW IB A A0A1DIF.MUX (TC514)CH1+CH2+CH3+CH4+CH1-CH2-CH3-CH4-CAP-CAP+(TC500TC500A)Converter SateTC500/A/510/5141.0ELECTRICALCHARACTERISTICSAbsolute Maximum Ratings†TC510/TC514 Positive Supply Voltage(V DD to GND).........................................+10.5V TC500/TC500A Supply Voltage(V DD to V SS)..............................................+18V TC500/TC500A Positive Supply Voltage(V DD to GND)............................................+12V TC500/TC500A Negative Supply Voltage(V SS to GND)................................................-8V Analog Input Voltage (V IN+ or V IN-)............V DD to V SS Logic Input Voltage...............V DD +0.3V to GND - 0.3V Voltage on OSC: ........................... -0.3V to (V DD +0.3V) for V DD < 5.5V Ambient Operating Temperature Range: ................................................................0°C to +70°C Storage Temperature Range:.............-65°C to +150°C † Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

During integration, analog switch S 1connects V IN to the integrator input where it is maintained for a fixed time period (T INT ). The application of V IN causes the integrator output to depart 0V at a rate determined by the magnitude of V IN and a direction determined by the polarity of V IN . The de-integration phase is initiated immediately at the expiration of T INT .During de-integration, S1 connects a reference voltage (having a polarity opposite that of V IN ) to the integrator input. At the same time, an external precision timer is started. The de-integration phase is maintained until the comparator output changes state, indicating the integrator has returned to its starting point of 0V. When this occurs, the precision timer is stopped. The de-integration time period (T DEINT ), as measured by the precision timer, is directly proportional to the magnitude of the applied input voltage (see Figure 4-3).A simple mathematical equation relates the input signal, reference voltage and integration time:EQUATION 4-1:For a constant V IN :EQUATION 4-2:The dual slope converter accuracy is unrelated to the integrating resistor and capacitor values as long as they are stable during a measurement cycle.An inherent benefit is noise immunity. Input noise spikes are integrated (averaged to zero) during the integration periods. Integrating ADCs are immune to the large conversion errors that plague successive approximation converters in high noise environments.Integrating converters provide inherent noise rejection with at least a 20dB/decade attenuation rate.Interference signals with frequencies at integral multiples of the integration period are, theoretically,completely removed, since the average value of a sine wave of frequency (1/T) averaged over a period (T) is zero.Integrating converters often establish the integration period to reject 50/60 Hz line frequency interference signals. The ability to reject such signals is shown by a normal mode rejection plot (Figure 4-1). Normal mode rejection is limited in practice to 50 to 65dB, since the line frequency can deviate by a few tenths of a percent (Figure 4-2).Normal Mode Rejection.Where:V REF =Reference VoltageT INT =Signal Integration time (fixed)t DEINT=Reference Voltage Integration time(variable)1R INT C INT -----------------------V IN T ()DT 0T INT ∫V REF C DEINT R INT C INT--------------------------------=V INV REF T DEINTT INT-----------------=TC500/A/510/514DS21428E-page 10© 2008 Microchip Technology Inc.FIGURE 4-3:Basic Dual Slope Converter.Phase ControlComparatorI n t e g r a t o r O u t p u tIntegrator C INTAnalog Input (V IN )Switch Driver Ref VoltageControl LogicPolarity Control S 1I/OTimer CounterROM RAMMicrocomputer AB CMPTR OutV SUPPLY ±T INTTC510V INTV IN ≈ V REFV IN ≈ 1/2 V REFT DEINT–+R INTV INT–+分销商库存信息:MICROCHIPTC510COG TC500CPE TC500COE TC500COE713TC510COG713TC514CPJTC514COI TC514COI713TC510EOG713 TC500IJE TC510CPF。
