ADC121S625CIMMX

Analog To Digital Converters (ADC) Overview

The ADC121S625CIMMX is a 12-bit, high-speed Analog-to-Digital Converter (ADC) from Texas Instruments. It features true differential inputs and supports sample rates from 50 ksps to 200 ksps. The device utilizes a Successive Approximation Register (SAR) architecture with an external reference input. It operates on a single +5V supply, consuming 2.25 mW at 200 ksps and dropping to 60 nW in power-down mode. The component communicates via a SPI/QSPI/MICROWIRE/DSP compatible serial interface and is housed in an 8-lead VSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIMMX' against the manufacturer's current product folder for availability status. Confirm that the 8-lead VSSOP package dimensions match the design requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the system environment. Check for any pin-compatible replacement notices or end-of-life notifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when differential input accuracy is required over single-ended configurations. Ensure the external reference voltage is between 100mV and 2.5V to define the input range. Verify that the system clock frequency can support up to 3.2 MHz for maximum throughput. Consider the 200 ksps maximum sample rate against the Nyquist requirement of the input signal bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC121S625 family, which includes variants like ADC121S625CIMM and ADC121S625CIMTX. The CIMMX designation specifically indicates the 8-lead VSSOP package variant. It serves as a pin-compatible replacement for older models such as the ADS7817. The device is designed for micro-power applications requiring direct sensor interfacing.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include ADC121S625CIMM/NOPB and ADC121S625CIMMX/NOPB. Verify if the '/NOPB' suffix denotes lead-free compliance without altering electrical characteristics. Cross-reference with the manufacturer's substitution guide for any discontinued versions within the same series.
