ADC121S051CIMFX

Analog To Digital Converters (ADC) Overview

The ADC121S051CIMFX is a single-channel, 12-bit analog-to-digital converter from Texas Instruments. It operates with a sample rate range of 200 ksps to 500 ksps and supports a supply voltage of 2.7V to 5.25V. The device utilizes a successive-approximation register architecture with an internal track-and-hold circuit. Power consumption is specified at 1.7 mW (typ) at 3.6V and 8.7 mW (typ) at 5.25V in normal mode. It features a serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. The component is available in 6-lead WSON and SOT-23 packages.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package suffix matches the required form factor: NGF for SOT-23 or DBV for WSON. Confirm the temperature grade corresponds to the industrial range of -40°C to +85°C. Ensure the ordering suffix aligns with the specific reel or tube packaging requirements of the distributor. Cross-reference the full part number against the manufacturer's current production status to confirm availability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution is required within the 200–500 ksps throughput range. It is suitable for applications requiring low power consumption under a single supply rail. Consider pin-compatible alternatives like the ADC121S021 for lower speeds or ADC121S101 for higher speeds if performance needs change. Ensure the input signal range matches the VA supply voltage.

Analog To Digital Converters (ADC) Part Context

The ADC121S051 is part of the ADC121SxxxA family of single-channel, 12-bit A/D converters. This family includes variants with different specified sample rates, such as the ADC121S021 (50–200 ksps) and ADC121S101 (500 ksps–1 Msps). All devices in this series are fully pin and function compatible, allowing for design flexibility across different speed requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the ADC121S021 for lower sample rates and the ADC121S101 for higher sample rates. These devices share the same package options and interface compatibility.
