Part Number: AD9744

Function: 14-Bit, 210 MSPS TxDAC D/A converter

Package: 28-lead SOIC, 28-lead TSSOP, and 32-lead LFCSP Type

Manufacturer: Analog Devices

Pinouts:

 

Description

The AD9744 is a 14-bit resolution, wideband, third generation member of the TxDAC series of high performance, low power CMOS digital-to-analog converters (DACs). The TxDAC family, consisting of pin-compatible 8-, 10-, 12-, and 14-bit DACs, is specifically optimized for the transmit signal path of communication systems. All of the devices share the same interface options, small outline package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost. The AD9744 offers exceptional ac and dc performance while supporting update rates up to 210 MSPS.

Features

1. High performance member of pin-compatible
2. TxDAC product family
3. Excellent spurious-free dynamic range performance
4. SFDR to Nyquist
5. 83 dBc at 5 MHz output
6. 80 dBc at 10 MHz output
7. 73 dBc at 20 MHz output
8. SNR at 5 MHz output, 125 MSPS: 77 dB
9. Twos complement or straight binary data format
10. Differential current outputs: 2 mA to 20 mA
11. Power dissipation: 135 mW at 3.3 V
12. Power-down mode: 15 mW at 3.3 V
13. On-chip 1.2 V reference
14. CMOS-compatible digital interface
15. Edge-triggered latches

Applications

1. Wideband communication transmit channel
2. Direct IFs
3. Base stations
4. Wireless local loops
5. Digital radio links
6. Direct digital synthesis (DDS)
7. Instrumentation
