Description

The AD9144 is a quad, 16-bit, high dynamic range digital-to analog converter (DAC) that provides a maximum sample rate of 2.8 GSPS, permitting a multicarrier generation up to the Nyquist frequency.

The DAC outputs are optimized to interface seamlessly with the ADRF672x analog quadrature modulators (AQMs) from Analog Devices, Inc. An optional 3-wire or 4-wire serial port interface (SPI) provides for programming/readback of many internal parameters. Full-scale output current can be programmed over a typical range of 13.9 mA to 27.0 mA. The AD9144 is available in an 88-lead LFCSP.

Features : 

1. Supports input data rate >1 GSPS

2. Multiple chip synchronization

3. Input signal power detection

4. Digital inverse sinc filter
