The AD9763/AD9765/AD9767 are 10-/12-/14-bit dual-channel digital-to-analog converters (DACs) with a 125 MSPS update rate. They offer excellent SFDR performance, high gain and offset matching, fully independent or single-resistor gain control, etc.
The AD9763/AD9765/AD9767 family provides two high‑performance TxDAC+® cores in a single 48‑lead LQFP package. Each part supports dual‑port or interleaved data input, independent gain control, and on‑chip 1.20 V temperature‑compensated reference. They are optimized for I/Q data processing in communications, digital synthesis, and ultrasound applications.
Typical applications include base‑station transmitters, quadrature modulation, and VDSL systems. The devices operate from a single 3.3 V to 5 V supply, consume low power, and offer excellent SFDR, gain matching, and low offset error, making them suitable for high‑precision analog output requirements.
