The AD9714/AD9715/AD9716/AD9717 are pin-compatible, dual, 8-/10-/12-/14-bit TxDAC digital-to-analog converters (DACs) that provide differential current outputs and operate in the 1.8 V to 3.3 V supply voltage range. The devices feature 2 on-chip auxiliary DACs with single-port operation and are available in a small 40-lead LFCSP package.
The AD9714‑AD9717 family are dual, low‑power, 8‑ to 14‑bit digital‑to‑analog converters (TxDAC) optimized for transmit paths in communication systems. They operate from a single 1.8 V to 3.3 V supply and deliver up to 125 MSPS sample rates with low power dissipation.
The document provides detailed electrical specifications, functional block diagrams, pin configurations, SPI interface details, and ordering guides for the 40‑lead LFCSP package. Application notes include wireless infrastructure, medical instrumentation, and portable test equipment.
