AD766 is a 16-bit DSP DACPORT that provides a direct, three-wire interface to the serial ports of popular DSP processors, including the ADSP-2101, TMS320CXX, and DSP56001.
The AD766 provides a direct three‑wire interface to popular DSP processors such as the ADSP‑2101, TMS320CXX and DSP56001, eliminating the need for external glue logic. It integrates a serial‑to‑parallel converter, a 16‑bit current‑steering DAC, a precision voltage reference, and an on‑chip output op‑amp.
Designed in Analog Devices’ BiMOS II mixed‑signal process, the device operates from ±5 V to ±12 V, offers up to 12.5 MHz serial clock rates, and includes features such as short‑circuit protection, ESD Category 1 classification, and selectable temperature grades for commercial, industrial, and military applications.
