PRODUCT DESCRIPTION\nThe 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.\nThe AD565A and AD566A use 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.\nThe combination of performance and flexibility in the AD565A and AD566A 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 and AD566A have a 10–90% full-scale transition time less than 35 ns and settle to within ±1/2 LSB in 250 ns max (350 ns for AD566A). Both are laser-trimmed at the wafer level to ±1/8 LSB typical linearity and are specified to ±1/4 LSB max error (K and T grades) at +25°C. High speed and accuracy make the AD565A and AD566A the ideal choice for high-speed display drivers as well as fast analog-to-digital converters.FEATURES\n  Single Chip Construction\n  Very High-Speed Settling to 1/2 LSB\n     AD565A: 250 ns max\n     AD566A: 350 ns max\n  Full-Scale Switching Time: 30 ns\n  Guaranteed for Operation with ±12 V Supplies:\n     AD565A with –12 V Supply: AD566A\n  Linearity Guaranteed Over Temperature:\n     1/2 LSB max (K, T Grades)\n  Monotonicity Guaranteed Over Temperature\n  Low Power: AD566A = 180 mW max;\n                      AD565A = 225 mW max\n  Use with On-Board High-Stability Reference (AD565A) or with External Reference (AD566A)\n  Low Cost\n  MlL-STD-883-Compliant Versions Available
