The AD660 DACPORT® is a 16-bit serial/byte monolithic digital-to-analog converter (DAC) with the following features: complete 16-bit digital-to-analog function, on-chip output amplifier, on-chip buried Zener voltage reference, ±1 LSB integral linearity, 15-bit monotonic over temperature, microprocessor compatible, serial or byte input, double-buffered latches, fast (40 ns) write pulse, asynchronous clear (to 0 V) function, serial output pin facilitates daisy-chaining, unipolar or bipolar output, low glitch: 15 nV-s, low total harmonic distortion (THD) + noise: 0.009%
The AD660 DACPORT® is a complete 16‑bit DAC that integrates a voltage reference, double‑buffered latches and an output amplifier on a single chip. It supports serial or byte input, daisy‑chaining, and provides both unipolar (0 V‑10 V) and bipolar (‑10 V‑+10 V) output ranges. The device is manufactured on Analog Devices' BiMOS II process and guarantees 15‑bit monotonicity over temperature.
The datasheet details electrical specifications such as 16‑bit resolution, ±1 LSB INL/DNL, 0.009 % THD+N, and timing parameters down to 40 ns. It also includes layout recommendations, power‑supply decoupling guidelines, and configuration examples for unipolar and bipolar operation, making it suitable for high‑precision instrumentation and control applications.
| Resolution | 16 bits |
|---|---|
| tCS (Serial Load Timing) | 40 ns min |
| Absolute Maximum +VCC to AGND | −0.3 V to +17.0 V |
Typical supplies are +VCC = 15 V, –VEE = –15 V, and +VLL = 5 V, with allowable ranges shown in the absolute‑maximum ratings.
Tie REF OUT directly to REF IN and SPAN/BIPOLAR OFFSET directly to VOUT; this config provides a 0 V‑10 V output without external parts.
