AD9114-EBZ中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The AD9114/AD9115/AD9116/AD9117 are pin-compatible dual, 8-/10-/12-/14-bit, low power digital-to-analog converters (DACs) that provide a sample rate of 125 MSPS. These TxDAC® converters are optimized for the transmit signal path of communication systems. All the devices share the same interface, LFCSP, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost.
