AD9114/AD9115/AD9116/AD9117 are low power, 8-bit to 14-bit TxDAC digital-to-analog converters with low power consumption and high performance.
The AD9114/AD9115/AD9116/AD9117 family are pin‑compatible dual DACs that provide up to 14‑bit resolution and a maximum sample rate of 125 MSPS. They operate from a single 1.8 V to 3.3 V supply and feature low power dissipation (191 mW @10 MSPS, 232 mW @125 MSPS) with sleep mode below 3 mW.
These converters are intended for wireless infrastructure, picocell/femtocell base stations, medical instrumentation, portable test equipment, and signal‑generator applications. The ordering guide lists the 40‑lead LFCSP package options and evaluation board part numbers.
| Resolution | 8‑14 bits |
|---|---|
| Supply Voltage Range | 1.8 V to 3.3 V |
| Power Dissipation (125 MSPS) | 232 mW |
| Output Current (AVDD = 3.3 V) | 2 mA to 8 mA |
| Output Noise (20 mA) | 1471 pA/√Hz |
The AD9114 operates from a single supply of 1.8 V to 3.3 V.
At 125 MSPS the AD9114 dissipates about 232 mW.
With AVDD = 3.3 V the DAC can source 2 mA to 8 mA per output.
