Product Overview

The AD585AQ is a complete monolithic Sample and Hold Amplifier consisting of a high performance Op-amp in series with an ultralow leakage analog switch and a FET input integrating amplifier. An internal holding capacitor and matched applications resistors have been provided for high precision and applications flexibility. The performance of the AD585 makes it ideal for high speed 10- and 12-bit data acquisition systems, where fast acquisition time, low sample-to-hold offset and low droop are critical. The AD585 can acquire a signal to ±0.01% in 3ms maximum and then hold that signal with a maximum sample-to-hold offset of 3mV and less than 1mV/ms droop, using the on-chip hold capacitor. If lower droop is required, it is possible to add a larger external hold capacitor. The high speed analog switch used in the AD585 exhibits aperture jitter of 0.5ns, enabling the device to sample full scale (20V peak-to-peak) signals at frequencies up to 78kHz with 12-bit precision.
