Dual Low Power, 8-Bit TxDAC Digital-to-Analog Converters

Manufactured by:

Product Details

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 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.

Product Details

This user guide describes the AD911x and AD971x evaluation boards, which provide all of the support circuitry required to operate the AD911x and AD971x in their various modes and configurations. The application software used to interface with the devices is also described.

The AD9114/AD9115/AD9116/AD9117 and AD9714/AD9715/AD9716/AD9717 data sheets should be consulted when using the evaluation board. The AD971x/AD911x Rev. A evaluation board operates together with the Data Pattern Generator 2 (DPG2) and the DAC software suite, including the AD971x/AD911x update.

The CD-ROM provided with the evaluation board includes the installation program for all necessary software. The install program can also be downloaded. Both methods install the DPGDownloader program for loading vectors as well as the AD971x/AD911x update necessary for SPI communication.
