Overview
The ADS8588SIPMR, produced by Texas Instruments, is a 16-bit, high-speed, 8-channel analog-to-digital converter (ADC) designed for integrated data acquisition (DAQ) systems. This device operates on a simultaneous-sampling basis, utilizing a successive approximation (SAR) ADC architecture. It supports a maximum sample rate of 200 kSPS per channel and is configured to accept ±10 V and ±5 V true bipolar inputs using a single 5-V supply. The ADS8588SIPMR features a complete analog front-end for each channel, including a programmable gain amplifier (PGA), input clamp, low-pass filter, and an ADC input driver. This makes it an ideal choice for various industrial automation and control applications due to its high performance, accuracy, and zero-latency conversions.
