ADC08032CIWMX

Analog To Digital Converters (ADC) Overview

The ADC08032CIWMX is an obsolete 8-bit successive approximation analog-to-digital converter manufactured by Texas Instruments. It features a 14-pin SOIC package and operates on a single 5V supply (4.5V to 6.3V). The device includes two configurable analog input channels supporting single-ended, differential, or pseudo-differential modes. It utilizes a serial interface compatible with the NSC MICROWIRE standard for data exchange. Key electrical specifications include a maximum conversion time of 8 μs at a 1 MHz clock frequency, a total unadjusted error of ±1 LSB, and power dissipation of 20 mW.

Analog To Digital Converters (ADC) Procurement Notes

This component is officially classified as obsolete by Texas Instruments. Availability is restricted to existing stock or third-party distributors; direct procurement from the manufacturer is not possible. Verify the specific revision level and packaging details when sourcing from secondary markets, as production data reflects historical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this part only if legacy compatibility with the ADC0803x family is required. Note that the ADC08032 lacks an external band-gap reference pin, relying instead on the internal connection to VCC. Ensure the application supports the 4.5V to 6.3V operating range and can accommodate the 14-pin SOIC footprint.

Analog To Digital Converters (ADC) Part Context

The ADC08032CIWMX belongs to the ADC08031/ADC08032/ADC08034/ADC08038 series. It shares architectural similarities with the ADC0832 but differs in package options and specific interface timing requirements defined by the NSC MICROWIRE standard. The 'CIWM' suffix indicates industrial temperature range and tape-and-reel packaging.

Analog To Digital Converters (ADC) Replacement Considerations

No direct active replacements are listed in the provided documentation. Legacy designs may consider the ADC0832CCWM-NOPB for similar functionality, though interface timing and pin configurations differ. Consult Texas Instruments for current generation alternatives.
