ADC121S021CIMF/NOPB Description

Short technical summary and product information.

The ADC121S021CIMF/NOPB is a single-channel, 12-bit successive-approximation register (SAR) analog-to-digital converter from Texas Instruments. It is specified over a sample rate range of 50 ksps to 200 ksps and accepts a single-ended analog input with an input voltage range from 0 V to 5.25 V. The device uses a supply reference and operates from analog and digital supplies ranging from 2.7 V to 5.25 V.

 

This ADC features a high-speed serial interface compatible with SPI, QSPI, MICROWIRE, and common DSP serial interfaces. Typical dynamic performance includes a signal-to-noise ratio of 72.3 dB, with differential nonlinearity of 0.45/−0.25 LSB and integral nonlinearity of 0.45/−0.4 LSB. Power consumption is 1.5 mW typical at a 3.6 V supply and 7.9 mW typical at 5.25 V.

 

The converter is housed in a surface-mount SOT-23-6 package and supports an operating temperature range of −40°C to 85°C. Its single-supply operation and small package size make it suitable for space-constrained precision measurement and data acquisition applications.
