AD9148 Quad 16-Bit,1GSPS DAC TxDAC+® Digital-to-Analog Converter
Product Highlights
1. Low noise and inter-modulation 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 singleended
or differential circuit topologies.
4. LVDS data input interface includes FIFO to ease input timing.
Applications
The AD9148 is a quad, 16-bit, high dynamic range, digital-toanalog
converter (DAC) that provides a sample rate of 1000 MSPS.
These devices include features optimized for direct conversion
transmit applications, including gain, phase, and offset compensation.
The DAC outputs are optimized to interface seamlessly with
analog quadrature modulators such as the ADL5371/ADL5372/
ADL5373/ADL5374/ADL5375/. A serial peripheral interface (SPI)
is provided for programming of the internal device parameters.
Full-scale output current can be programmed over a range of 10 mA
to 30 mA. The devices operate from 1.8 V and 3.3 V supplies for
a total power consumption of 3 W at the maximum sample rate.
They are enclosed in 196-ball chip scale package ball grid array
with the option of an attached heat spreader..
