The AD9708 is the 8-bit resolution member of the TxDAC series of high performance, low power CMOS digital-to-analog converters (DACs). The TxDAC family provides high resolution, low power, high update rate, and low noise performance, making it an ideal choice for communications, signal reconstruction, and instrumentation applications.
The AD9708 belongs to Analog Devices’ TxDAC family and provides an 8‑bit resolution DAC optimized for transmit signal paths in communication systems. It features a proprietary switching technique, edge‑triggered input latches, and an on‑chip 1.20 V bandgap reference, delivering up to 20 mA full‑scale output current.
The device is offered in 28‑lead SOIC and TSSOP packages, operates from +2.7 V to +5.5 V supplies, and supports update rates up to 125 MSPS. Detailed DC, dynamic, and absolute‑maximum specifications are provided, along with pin configurations, ordering information, and application notes for both single‑ended and differential outputs.
