Product Summary

The AD7859LAS is a high speed, low power, 8-channel, 12-bit ADC which operates from a single 3V or 5V power supply. The AD7859LAS contains self-calibration and system calibration options to ensure accurate operation over time and temperature and have a number of power-down options for low power applications. The applications of the AD7859LAS include Battery-Powered Systems (Personal Digital Assistants, Medical Instruments, and Mobile Communications), Pen Computers, Instrumentation and Control Systems, High Speed Modems.
