GENERAL DESCRIPTION
The AD9714/AD9715/AD9716/AD9717 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 AD9714/AD9715/AD9716/AD9717 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 AD9714/AD9715/AD9716/AD9717
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 35 mW at 125 MSPS with a 1.8 V
supply. 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
easy interfacing to other components that accept common-
mode levels greater than 0 V.
