Overview
The AD9114BCPZRL7, produced by Analog Devices Inc., is part of the AD9114/AD9115/AD9116/AD9117 family of dual, low power digital-to-analog converters (DACs). These TxDAC® converters are optimized for the transmit signal path of communication systems and offer exceptional ac and dc performance. They support sample rates up to 125 MSPS, making them suitable for high-speed applications. The AD9114BCPZRL7 is specifically an 8-bit DAC, sharing the same interface, package, and pinout as its 10-bit, 12-bit, and 14-bit counterparts, allowing for flexible component selection based on performance, resolution, and cost.
