GENERAL DESCRIPTION
The AD9146 is a dual, 16-bit, high dynamic range digital-to-
analog converter (DAC) that provides a sample rate of 1000 MSPS
with nominal supplies and 1230 MSPS with increased supplies,
permitting multicarrier generation up to the Nyquist frequency.
The AD9146 TxDAC+ includes features optimized for direct
conversion transmit applications, including complex digital mod-
ulation, and gain and offset compensation. The DAC outputs
are optimized to interface seamlessly with analog quadrature
modulators, such as the ADL537x F-MOD series from Analog
Devices, Inc. A 3-wire serial port interface provides for program-
ming/readback of many internal parameters. Full-scale output
current can be programmed over a range of 8.7 mA to 31.7 mA.
The AD9146 comes in a 48-lead LFCSP.
PRODUCT HIGHLIGHTS
1. Ultralow noise and intermodulation distortion (IMD)
enable high quality synthesis of wideband signals from
baseband to high intermediate frequencies (IF).
2. Proprietary DAC output switching technique enhances
dynamic performance.
3. Current outputs are easily configured for various single-
ended or differential circuit topologies.
4. Compact LVDS digital interface offers reduced width
data bus.
