DESCRIPTION/ORDERING INFORMATION

The DAC5652 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 200 MSPS, the DAC5652 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 DAC5652 has two 10-bit parallel input ports with separate clocks and data latches. For flexibility, the

DAC5652 also supports multiplexed data for each DAC on one port when operating in the interleaved mode.

The DAC5652 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.
