The AD9761 is a complete dual-channel, high speed, 10-bit CMOS DAC. The AD9761 has been developed specifically for use in wide bandwidth communication applications (e.g., ...).
The AD9761 is a high‑speed, dual‑channel 10‑bit transmit DAC designed for wide‑bandwidth communication systems. It integrates two 10‑bit DACs, dual 2× interpolation filters, an on‑chip 1.2 V band‑gap reference, and a flexible digital interface supporting I and Q data streams.
The device operates from a single 3 V‑5.5 V supply, delivers up to 10 mA full‑scale output current per channel, and achieves up to 71 dB spurious‑free dynamic range with an ENOB of 9.5 bits. Detailed specifications, pin descriptions, and typical performance curves are provided for designers.
