ADC08134CIWMX

Analog To Digital Converters (ADC) Overview

The ADC08134CIWMX is an obsolete 8-bit successive approximation analog-to-digital converter manufactured by Texas Instruments. It features a 4-channel input multiplexer with configurable single-ended, differential, or pseudo-differential modes. The device operates on a single 5V supply (4.5V to 6.3V) and includes an internal 2.5V band-gap voltage reference. Key electrical specifications include a maximum conversion time of 8 µs at a 1 MHz clock frequency, a maximum power dissipation of 20 mW, and a total unadjusted error of ±1 LSB. It utilizes a serial digital data link compatible with MICROWIRE standards.

Analog To Digital Converters (ADC) Part Context

The ADC08134CIWMX belongs to the ADC0813x family, which also includes the ADC08131 (1 channel) and ADC08138 (8 channels). All variants share identical core architecture, resolution, and performance characteristics, differing primarily in the number of available analog input channels and corresponding package pin counts.

Analog To Digital Converters (ADC) Replacement Considerations

This component is marked as OBSOLETE by Texas Instruments. Designers should consult current product selection guides for modern replacements within the same family or alternative high-speed serial ADCs that meet the required channel count and performance specifications.
