双通道， 8位/ 10位/ 12位/ 14位低功耗数字 - 模拟转换器 Dual, 8-/10-/12-/14-Bit Low Power Digital-to-Analog Converters
Product Details
The AD9114//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 commu-nication systems. All the devices share the same interface, package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost.
The AD9114/AD9115/AD9116/AD9117 offer exceptional ac and dc performance and support update rates up to 125 MSPS.
The flexible power supply operating range of 1.8 V to 3.3 V and low power dissipation of the AD9114/AD9115/AD9116/AD9117 make them well suited for portable and low power applications.
**Product Highlights**
1. Low Power. DACs operate on a single 1.8 V to 3.3 V supply; total power consumption reduces to 225 mW at 100 MSPS. Sleep and power-down modes are provided for low power idle periods.
2. CMOS Clock Input. High speed, single-ended CMOS clock input supports a 125 MSPS conversion rate.
3. Easy Interfacing to Other Components. Adjustable output common mode from 0 V to 1.2 V allows for easy interfacing to other components that accept common-mode levels greater than 0 V.
