Analog Devices AD9752AR

IC DAC 12BIT 125MSPS 28-SOIC / Bit Digital to Analog Converter 28-SOIC

DAC 1-CH Current Steering 12-Bit 28-Pin SOIC W

The AD9752 is a 12-bit resolution second generation member of the TxDAC series of high performance, low power CMOS digital-to-analog converters (DACs). The TxDAC family, which consists 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, thus providing an upward or downward component selection path based on performance, resolution and cost. The AD9752 offers exceptional ac and dc performance while supporting update rates up to 125 MSPS. APPLICATIONS Wideband Communication Transmit Channel: Direct IF Basestations Wireless Local Loop Digital Radio Link Direct Digital Synthesis (DDS) Instrumentation PRODUCT HIGHLIGHTS The AD9752 is a member of the wideband TxDACproduct family that provides an upward or downward component selection path based on resolution (8 to 14 bits), performance and cost. The entire family of TxDACs is available in industry standard pinouts. Manufactured on a CMOS process, the AD9752 uses a proprietary switching technique that enhances dynamic performance beyond that previously attainable by higher power/cost bipolar or BiCMOS devices. On-chip, edge-triggered input CMOS latches interface readily to +2.7 V to +5 V CMOS logic families. The AD9752 can support update rates up to 125 MSPS. A flexible single-supply operating range of 4.5 V to 5.5 V and a wide full-scale current adjustment span of 2 mA to 20 mA allow the AD9752 to operate at reduced power levels. The current output(s) of the AD9752 can be easily configured for various single-ended or differential circuit topologies.
