The AD766 is a 16-bit DSP DACPORT that provides a direct three-wire interface to the serial ports of popular DSP processors. It features a zero-chip interface, complete DACPORT on-chip voltage reference, voltage and current outputs, etc.
The AD766 16‑bit DSP DACPORT provides a three‑wire serial interface to popular DSP processors and includes an on‑chip voltage reference, current‑steering DAC, and output amplifier. It operates from +5 V to +12 V, offers up to 500 kSPS sample rates, and delivers up to +8 mA output current with short‑circuit protection.
Typical applications include digital signal processing, noise cancellation, radar jamming, automatic test equipment, precision industrial equipment and waveform generation. The device can be directly interfaced to ADSP‑2101, TMS320Cxx and DSP5600 series processors without additional glue logic.
