Overview
The ADC128S022CIMTX from Texas Instruments is a low-power, eight-channel CMOS 12-bit analog-to-digital converter (ADC). 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. The ADC128S022 is notable for its independent analog and digital supplies, with the analog supply (V_A) ranging from 2.7 V to 5.25 V and the digital supply (V_D) ranging from 2.7 V to V_A. The device is packaged in a 16-lead TSSOP package and operates over an extended industrial temperature range of –40°C to +105°C.
