Product Summary

The ADS8557IPM is a 16-, 14-, 12-Bit, Six-Channel, Simultaneous Sampling analog-to-digital converter. The ADS8557IPM contains six low-power, 16-, 14-, or 12-bit, successive approximation register (SAR) based analog-to-digital converters (ADCs) with true bipolar inputs, Each channel contains a sample-and-hold circuit that allows simultaneous high-speed multi-channel signal acquisition. The applications of the ADS8557IPM include Power Quality Measurement, Protection Relays, Multi-Axis Motor Control, Programmable Logic Controllers, and Industrial Data Acquisition.
