AD9114BCPZ

AD9114BCPZ is a dual low-power, 8-bit TxDAC digital-to-analogue converter. This TxDAC® converter is optimized for the transmit signal path of communication systems. The device shares the same interface, package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost. It is used in applications such as wireless infrastructures, picocell, femtocell base stations, medical instrumentation, ultrasound transducer excitation, portable instrumentation, signal generators, and arbitrary waveform generators.
