ADC122S051CIMM

Analog To Digital Converters (ADC) Overview

The ADC122S051CIMM is a Texas Instruments two-channel, 12-bit successive-approximation register (SAR) analog-to-digital converter. It operates with a single supply voltage ranging from +2.7V to +5.25V and supports sample rates between 200 ksps and 500 ksps. The device features an internal track-and-hold circuit and outputs straight binary data via a high-speed serial interface compatible with SPI, QSPI, and MICROWIRE standards. Key electrical specifications include a typical signal-to-noise ratio of 72.5 dB, integral non-linearity of ±0.5 LSB, and differential non-linearity of +0.7/-0.4 LSB. Normal power consumption is 3.0 mW at 3V and 10 mW at 5V.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix CIMM corresponds to the 8-lead VSSOP package and industrial temperature range (-40°C to +85°C). Confirm that the specific revision level matches the SNAS257E datasheet documentation. Ensure compatibility with the required serial clock frequency range of 3.2 MHz to 8 MHz for optimal performance specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 12-bit resolution is required within a compact 8-lead VSSOP footprint. It is suitable for designs needing variable power management and AEC-Q100 qualification. Compare against pin-compatible alternatives like the ADC122S021 for lower speed or ADC122S101 for higher throughput while maintaining identical pinouts.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC122S051 family, which includes variants such as the ADC122S051Q for automotive use. It shares pin and functional compatibility with other members of the series, allowing for design flexibility across different resolution and speed requirements without altering the PCB layout.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the ADC122S021 (50–200 ksps), ADC122S101 (500 ksps–1 Msps), and their 8-bit/10-bit counterparts. These devices maintain identical pinouts and functionality but differ in specified sampling rates.
