Texas Instruments  DAC5652AIPFB

The DAC5652A is a monolithic, dual-channel, 10-bit, high-speed digital-to-analogconverter (DAC) with on-chip voltage reference.

Operating with update rates of up to 275 MSPS, the DAC5652A offers exceptional dynamicperformance, tight-gain, and offset matching characteristics that make it suitable in either I/Qbaseband or direct IF communication applications.

Each DAC has a high-impedance, differential-current output, suitable for single-ended ordifferential analog-output configurations. External resistors allow scaling of the full-scaleoutput current for each DAC separately or together, typically between 2 mA and 20 mA. An accurateon-chip voltage reference is temperature-compensated and delivers a stable 1.2-V reference voltage.Optionally, an external reference may be used.

The DAC5652A has two, 10-bit, parallel input ports with separate clocks and data latches.For flexibility, the DAC5652A also supports multiplexed data for each DAC on one port whenoperating in the interleaved mode.

The DAC5652A has been specifically designed for a differential transformer-coupled outputwith a 50-Ω doubly-terminated load. For a 20-mA full-scale output current, both a 4:1 impedanceratio (resulting in an output power of 4 dBm) and 1:1 impedance ratio transformer (–2-dBm outputpower) are supported.

The DAC5652A is available in 48-pin TQFP and 48-pin VQFN packages. The TQFP packageoffers pin compatibility between family members that provides 10-bit (DAC5652A), 12-bit (DAC5662),and 14-bit (DAC5672) resolution. The TQFPpackage is also pin compatible to the DAC2900 and AD9763 dual DACs. The device ischaracterized for operation over the industrial temperature range of –40°C to +85°C.
