Description

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

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

Each DAC has a high-impedance, differential-current output, suitable for single-ended or differential analog-output configurations. External resistors allow scaling of the full-scale output current for each DAC separately or together, typically between 2 mA and 20 mA. An accurate on-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 when operating in the interleaved mode.

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

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