DESCRIPTION

· The TC530/TC534 are serial analog data acquisition subsystems designed for high precision measurements, offering up to 17-bit resolution plus sign.
· The TC534 includes a dual slope integrating A/D converter, a negative power supply generator, and a 3-wire serial interface port.
· The TC530 is similar to the TC534 but features a four-channel differential input multiplexer.
· Key parameters like Auto Zero and Integration time are programmable, allowing users to adjust conversion time for resolution.
· Data conversion starts when the RESET input is low, with data loaded into the output shift register and EOC asserted upon completion.
· The TC530/TC534 can operate with a single 5V power supply and provides a -5V, 10mA output for system components.

FEATURES

· Precision A/D Converter with up to 17-bit resolution.
· 3-Wire Serial Port for data communication.
· Flexible operation allowing trade-off between conversion speed and resolution.
· Single supply operation with a -5V output pin.
· 4 Input, Differential Analog MUX in TC530.
· Automatic input polarity and overrange detection.
· Low operating current, maximum of 5mA.
· Wide analog input range, up to ±4.2V.
· Cost-effective for precision applications.

APPLICATIONS

· Precision Analog Signal Processing.
· Precision Sensor Interface.
· High Accuracy DC Measurements.
