16-Bit Current-Steering DAC with Voltage Reference

Inquiry Add To Bom

AD766JNZ General Description

The AD766 16-bit DSP DACPORT provides a direct, three-wire interface to the serial ports of popular DSP processors, including the ADSP-2101, TMS320CXX, and DSP56001. No additional "glue logic" is required. The AD766 is also complete, offering on-chip serial-to-parallel input format conversion, a 16-bit current-steering DAC, voltage reference, and a voltage output op amp. The AD766 is fabricated in Analog Devices' BiMOS II mixed-signal process which provides bipolar transistors, MOS transistors, and thin-film resistors for precision analog circuits in addition to CMOS devices for logic.
