Product Details

The AD565A is a fast 12-bit digital-to-analog converter which incorporates the latest advances in analog circuit design to achieve high speeds.

The AD565A 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 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.

The combination of performance and flexibility in the AD565A has resulted from major innovations in circuit design, an important new high-speed bipolar process, and continuing advances in laser-wafer-trimming techniques (LWT). The AD565A have a 10-90% full-scale transition time less than 35 ns and settle to within ±1/2 LSB in 250 ns. It is laser-trimmed at the wafer level to ±1/8 LSB typical linearity. High speed and accuracy make the AD565A the ideal choice for high-speed display drivers as well as fast analog-to-digital converters.

The laser trimming process which provides the excellent linearity is also used to trim both the absolute value and the temperature coefficient of the reference of the AD565A resulting in a typical full-scale gain TC of 10 ppm/°C.
