TC835 - PERSONAL COMPUTER DATA ACQUISITION A/D CONVERTER

General Description

The TC835 is a low-power, 4-1/2 digit (0.005% resolution), BCD analog-to-digital converter (ADC) that has been characterized for 200 kHz clock rate operation.

The five conversions per second rate is nearly twice as fast as the ICL7135 or TC7135.

Key Features

  • s s s s s s s s Upgrade of Pin-Compatible TC7135, ICL7135, MAX7135 and SI7135 Guaranteed 200 kHz Operation Single 5V Operation With TC7660 Multiplexed BCD Data Output UART and Microprocessor Interface Control Outputs for Auto-Ranging Input Sensitivity 100 µV No Sample and Hold Required.

1 TC835 PERSONAL COMPUTER DATA ACQUISITION A/D CONVERTER FEATURES s s s s s s s s Upgrade of Pin-Compatible TC7135, ICL7135, MAX7135 and SI7135 Guaranteed 200 kHz Operation Single 5V Operation With TC7660 Multiplexed BCD Data Output UART and Microprocessor Interface Control Outputs for Auto-Ranging Input Sensitivity ............................................ 100 µV No Sample and Hold Required GENERAL DESCRIPTION The TC835 is a low-power, 4-1/2 digit (0.005% resolution), BCD analog-to-digital converter (ADC) that has been characterized for 200 kHz clock rate operation. The five conversions per second rate is nearly twice as fast as the ICL7135 or TC7135. The TC835 (like the TC7135) does not use the external diode-resistor roll-over error compensation circuits required by the ICL7135.
