PRODUCT DESCRIPTION The AD565A and AD566A are fast 12-bit digital-to-analog converters that incorporate the latest advances in analog circuit design to achieve high speeds at low cost. The AD565A and AD566A use 12 precision, high speed bipolar current-steering switches, a control amplifier, and a laser-trimmed thin-film resistor network to produce a very fast, high accuracy analog output current. The AD565A also includes a buried Zener reference that features low noise, long-term stability, and temperature drift characteristics comparable to the best discrete reference diodes.
