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 200kHz clock rate operation.

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

Key Features

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

TC835 Personal Computer Data Acquisition A/D Converter Features • • • • • • • • Upgrade of Pin-Compatible TC7135, ICL7135 200kHz Operation Single 5V Operation With TC7660 Multiplexed BCD Data Output UART and Microprocessor Interface Control Outputs for Auto-Ranging Input Sensitivity: 100µV 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 200kHz 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 rollover error compensation circuits required by the ICL7135. The multiplexed BCD data output is perfect for interfacing to personal computers.
