AD9744ARUZ 14-bit DAC/Digital to Analog Converter
The AD9744ARUZ is a high-speed 14-bit, 210 MSPS TxDAC® D/A converter designed by Analog Devices, optimized for wideband communication systems, radar, medical imaging, and instrumentation. This CMOS-based device operates across a supply voltage range of 2.7V to 3.6V, featuring a TSSOP-28 package with a compact 0.65mm terminal pitch. It delivers exceptional linearity (±0.0305% max error) and a 1.2V on-chip reference, ensuring precision in signal reconstruction. The chip supports edge-triggered latches, parallel binary/2's complement input formats, and operates reliably in industrial temperature ranges (-40°C to +85°C). With a power consumption of 135mW (3.3V active) and 15mW in power-down mode, it balances performance with energy efficiency. Applications include direct digital synthesis (DDS), base station transmitters, and wireless local loops.
