The ADC121S021CISDX/NOPB is a single-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments, designed for applications requiring low power consumption and a wide range of sample rates. It operates within a sample rate range of 50 to 200 ksps and features a high-speed serial interface compatible with SPI, QSPI, MICROWIRE, and various DSP interfaces. The device is powered by a single supply voltage ranging from 2.7 V to 5.25 V, with typical power consumption of 1.5 mW at 3.6 V and 7.9 mW at 5.25 V. A power-down mode reduces consumption to as low as 2.6 ¬µW. The ADC121S021 is housed in a compact 6-pin WSON package and is rated for operation over an industrial temperature range of -40¬8C to 85¬8C. Key performance specifications include a typical differential nonlinearity (DNL) of 0.45 LSB and an integral nonlinearity (INL) of 0.45 LSB, along with a signal-to-noise ratio (SNR) of 72.3 dB. This device is suitable for portable systems, remote data acquisition, and instrumentation applications.
