ADC08832

ADC08831, ADC08832 www.ti.com SNAS015C – SEPTEMBER 1999 – REVISED MARCH 2013 ADC08831 /ADC08832 8-Bit Serial I/O CMOS A/D Converters with Multiplexer and Sample/Hold Function Check for Samples: ADC08831, ADC08832 FEATURES 1 2 3-Wire Serial Digital Data Link Requires Few I/O Pins Analog Input Track/Hold Function 2-Channel Input Multiplexer Option with Address Logic Analog Input Voltage Range from GND to VCC No Zero or Full Scale Adjustment Required TTL/CMOS Input/Output Compatible Superior Pin Compatible Replacement for ADC0831/2 APPLICATIONS Digitizing Sensors and Waveforms Process Control Monitoring Remote Sensing in Noisy Environments Instrumentation Embedded Systems DESCRIPTION The ADC08831/ADC08832 are 8-bit successive approximation Analog to Digital converters with 3-wire serial interfaces and a configurable input multiplexer for 2 channels. The serial I/O will interface to COPSfamily of micro-controllers, PLD's, microprocessors, DSP's, or shift registers. The serial I/O is configured to comply with the MICROWIRE serial data exchange standard. To minimize total power consumption, the ADC08831/ADC08832 automatically go into low power mode whenever they are not performing conversions. A track/hold function allows the analog voltage at the positive input to vary during the actual A/D conversion. The analog inputs can be configured to operate in various combinations of single-ended, differential, or pseudo-differential modes. The voltage reference...
