Overview
The ADC128S052CIMTX/NOPB, produced by Texas Instruments, is a low-power, eight-channel CMOS 12-bit analog-to-digital converter (ADC). This device is designed for high conversion throughput rates of 200 kSPS to 500 kSPS and is based on a successive-approximation register (SAR) architecture with an internal track-and-hold circuit. It can accept up to eight input signals at inputs IN0 through IN7 and is packaged in a 16-pin TSSOP package. The ADC128S052CIMTX/NOPB is suitable for a wide range of applications due to its independent analog and digital supplies, variable power management, and compatibility with several serial interface standards such as SPI, QSPI, MICROWIRE, and common DSP serial interfaces.
