ADC08134CIWM

Analog To Digital Converters (ADC) Overview

The ADC08134CIWM is an obsolete 8-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a serial digital data link requiring few I/O pins and includes a configurable 4-channel input multiplexer with address logic. The device operates on a single 5V supply, providing a 0V to 5V analog input range. Key specifications include a maximum conversion time of 8 µs at a 1 MHz clock frequency and a total unadjusted error of ±1 LSB. An internal 2.5V band-gap reference ensures performance over temperature variations.

Analog To Digital Converters (ADC) Procurement Notes

This component is officially classified as obsolete by the manufacturer. Verification of availability requires checking distributor stock lists for remaining inventory or identifying qualified replacement parts from current product lines. Ensure that any substitute components maintain compatibility with the required 8-bit resolution, serial interface protocol, and voltage levels.

Analog To Digital Converters (ADC) Selection Notes

Select this part when a low pin-count solution for multi-channel signal acquisition is required. The ADC08134CIWM supports both single-ended and differential input configurations via software-controlled addressing. Designers must account for the 8 µs conversion latency and ensure the host processor can handle the serial data timing constraints defined in the datasheet.

Analog To Digital Converters (ADC) Part Context

The ADC08134CIWM belongs to the ADC0813x family, which also includes the ADC08131 (1 channel) and ADC08138 (8 channels). All variants share the same SAR architecture and serial interface but differ in multiplexer channel count and package pin configuration. The 'CIWM' suffix indicates a commercial temperature range (-40°C to +85°C) and a Small Outline Integrated Circuit (SOIC) package.
