Overview
The ADC104S021CIMMX/NOPB, produced by Texas Instruments, is a low-power, four-channel CMOS 10-bit analog-to-digital converter (ADC) with a high-speed serial interface. This ADC is based on a successive-approximation register (SAR) architecture and includes an internal track-and-hold circuit. It is designed to operate over a sample rate range of 50 ksps to 200 ksps, making it versatile for various applications. The device can accept up to four input signals and provides output serial data in straight binary format, compatible with standards such as SPI™, QSPI™, MICROWIRE, and common DSP serial interfaces.
