TC500/A/510/514

Precision Analog Front Ends with Dual Slope ADC

Features:

General Description:

• Precision (up to 17 bits) A/D Converter “Front

End”

TheTC500/A/510/514 family are precision analog front

ends that implement dual slope A/D converters having

a maximum resolution of 17 bits plus sign. 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.

• 3-Pin Control Interface to Microprocessor

• Flexible: User Can Trade-off Conversion Speed

for Resolution

• Single-Supply Operation (TC510/TC514)

• 4 Input, Differential Analog MUX (TC514)

• Automatic Input Voltage Polarity Detection

• Low Power Dissipation:

- (TC500/TC500A): 10 mW

- (TC510/TC514): 18 mW

• Wide Analog Input Range:

- ±4.2V (TC500A/TC510)

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.

• Directly Accepts Bipolar and Differential

Input Signals

Applications:

• Precision Analog Signal Processor

• Precision Sensor Interface

• High Accuracy DC Measurements

The TC500/A/510/514 offer high resolution (up to

17 bits), superior 50/60 Hz 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.
