Overview
The ADC108S022CIMT, produced by Texas Instruments, is a low-power, eight-channel CMOS 10-bit analog-to-digital converter (ADC). It is designed for conversion throughput rates ranging from 50 ksps to 200 ksps. The converter utilizes a successive-approximation register architecture with an internal track-and-hold circuit, allowing it to accept up to eight input signals at inputs IN0 through IN7. The device is packaged in a 16-lead TSSOP package and operates over an extended industrial temperature range of −40°C to +105°C.
