Product Summary

The AD565ATD is a fast 12-bit digital-to-analog converter that incorporates the latest advances in analog circuit design to achieve high speeds at low cost. The AD565ATD uses 12 precision, high-speed bipolar current-steering switches, control amplifier and a laser-trimmed thin-film resistor network to produce a very fast, high accuracy analog output current. The AD565ATD also includes a buried Zener reference that features low-noise, long-term stability and temperature drift characteristics comparable to the best discrete reference diodes.
