GENERAL DESCRIPTION
The AD9148 is a quad, 16-bit, high dynamic range, digital-to-
analog converter (DAC) that provides a sample rate of 1000 MSPS.
This device includes features optimized for direct conversion
transmit applications, including gain, phase, and offset compen-
sation. The DAC outputs are optimized to interface seamlessly with
analog quadrature modulators such as the ADL5371/ADL5372/
is provided for programming of the internal device parameters.
Full-scale output current can be programmed over a range of 8.7 mA
to 31.7 mA. The device operates from 1.8 V and 3.3 V supplies
for a total power consumption of 3 W at the maximum sample
rate. The AD9148 is enclosed in a 196-ball chip scale package ball
grid array with the option of an attached heat spreader.
PRODUCT HIGHLIGHTS
1. Low noise and intermodulation distortion (IMD) enable
high quality synthesis of wideband signals from baseband
to high intermediate frequencies.
2. A proprietary DAC output switching technique enhances
dynamic performance.
3. The current outputs are easily configured for various
single-ended or differential circuit topologies.
4. The LVDS data input interface includes FIFO to ease input
timing.
