ADC121S021CIMF

Analog To Digital Converters (ADC) Overview

The ADC121S021CIMF is a single-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture with an integrated sample-and-hold circuit. The device supports data rates ranging from 50 ksps to 200 ksps and operates on a supply voltage between 2.7V and 5.25V. Communication is handled via a standard SPI or DSP-compatible serial interface. It is housed in a compact SOT-23-6 surface-mount package and is rated for operation within a temperature range of -40°C to +85°C.
