AD9144BCPZ

The AD9144 is a quad, 16-bit, high dynamic rangeDigital-to-analog converters(DAC), which provides a maximum sampling rate of 2.8 GSPS and can generate multiple carriers up to the Nyquist frequency. The DAC output is optimized to interface seamlessly with Analog Devices' ADRF672x analog quadrature modulator (AQM). An optional 3-wire or 4-wire serial port interface (SPI) allows programming and readback of many internal parameters. The full-scale output current can be programmed from 13.9 mA to 27.0 mA typically. The AD9144 is available in an 88-lead LFCSP package.

Product features

1. Ultra-wide complex signal bandwidth above 1 GHz to support emerging wideband and multiband wireless applications.
2. Advanced low-spurious and distortion design techniques enable high-quality synthesis of wideband signals from baseband to high IF signals.
3. Support for JESD204B subclass 1 simplifies multichip synchronization in software and hardware designs.
4. For data interface widths with serializer/deserializer (SERDES) JESD204B 8-channel interface, fewer pins are required.
5. Programmable transmit enable makes it easy to balance power consumption with wake-up time.
6. Small package sizes 12 mm × 12 mm.
