Overview
The ADC108S022CIMTX/NOPB, produced by Texas Instruments, is a low-power, eight-channel CMOS 10-bit analog-to-digital converter. This device is designed for conversion throughput rates ranging from 50 ksps to 200 ksps and is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can accept up to eight input signals at inputs IN0 through IN7 and provides output serial data in straight binary format, compatible with several standards including SPI, QSPI, MICROWIRE, and many common DSP serial interfaces. The ADC108S022CIMTX/NOPB operates with independent analog and digital supplies, supporting a wide range of voltage inputs and featuring a power-down mode to significantly reduce power consumption.
