ADC121S625CIMM/J7001348

Analog To Digital Converters (ADC) Overview

The ADC121S625CIMM/J7001348 is a 12-bit, 50 ksps to 200 ksps sampling Analog-to-Digital Converter (ADC) from Texas Instruments. It features true differential inputs and an external reference input. The device operates on a single +5V supply with analog and digital voltage ranges of 4.5V to 5.5V. It utilizes a SAR architecture and communicates via SPI/QSPI/MICROWIRE/DSP compatible serial interfaces. Key electrical parameters include a typical SNR of 72.9 dB, offset error of 0.4 LSB, gain error of 0.05 LSB, INL of ±1 LSB max, and DNL of ±0.75 LSB max. Power consumption is 2.25 mW at 200 ksps and drops to 60 nW in power-down mode.
