Product details

The AD9764 belongs to the TxDAC® family of high performance, low power CMOSDigital-to-analog converters(DAC) 14-bit resolution product. The TxDAC® family consists of pin-compatible 8-, 10-, 12-, and 14-bit DACs optimized for the transmit signal path of communication systems. All devices share the same interface options, small packages, and pinouts, allowing you to go up or down to select the right device based on performance, resolution, and cost. The AD9764 provides excellent ac and dc performance while supporting update rates up to 125 MSPS.

The flexible single-supply operating voltage range (2.7 V to 5.5 V) and low power consumption of the AD9764 make it ideal for portable and low power applications. By reducing the full-scale current output, the power consumption can be further reduced to only 45 mW with only a slight decrease in performance. In addition, standby power consumption can be reduced to approximately 25 mW in power-down mode.

The AD9764 is manufactured using an advanced CMOS process. The segmented current source architecture, combined with proprietary switching technology, reduces spurious components and enhances dynamic performance. The device also integrates edge-triggered input latches and a 1.2 V temperature-compensated bandgap reference, providing a complete monolithic DAC solution. Flexible power options support +3 V and +5 V CMOS logic families.

The AD9764 is a current output DAC with a nominal full-scale output current of 20 mA and an output impedance greater than 100 kΩ. It provides differential current outputs to support single-ended or differential applications. Matching between the two current outputs ensures enhanced dynamic performance in differential output configurations. The current output can be connected directly to an output resistor to provide two complementary single-ended voltage outputs or fed directly into the transformer. The compatible output voltage range is 1.25 V.

The on-chip reference and control amplifier are configured for maximum accuracy and flexibility. The AD9764 can be driven by an on-chip reference voltage or a variety of different external references. The internal control amplifier provides a wide (>10:1) adjustment range, allowing the full-scale current of the AD9764 to be adjusted from 2 mA to 20 mA while maintaining excellent dynamic performance. As a result, the AD9764 can operate at low power levels or be adjusted in the 20 dB range, further providing gain range adjustment.

The AD9764 is available in a 28-lead SOIC package and is specified over the industrial temperature range.
