Overview

The ADS8588SIPMR is a high-performance 16-bit data acquisition system featuring eight channels of simultaneous sampling SAR ADCs. It integrates a complete analog front-end for each channel, including a programmable gain amplifier (PGA) with high 1-Megohm input impedance and an overvoltage clamp. This device is designed to handle bipolar input ranges up to +/-10V while operating from a single 5V supply.

Why Choose This Part

The integrated high-impedance PGA allows direct connection to sensors without external buffer circuitry, significantly reducing PCB footprint. Its ability to sample all eight channels simultaneously at 16-bit resolution ensures no phase delay between signals, which is critical for vector control and power monitoring.

Applications

Power Grid Monitoring
Simultaneous sampling of three-phase voltage and current waveforms for precise power quality analysis and protection relays.
Multi-Axis Motor Control
Synchronous sensing of multiple motor phases and position sensors to ensure tight control loops in industrial automation.
Industrial Data Acquisition
Interfacing with high-voltage sensors in harsh environments thanks to the integrated +/-15V input clamps and 7-kV ESD protection.
