DESCRIPTION

The DAC5662 is a monolithic, dual-channel 12-bit, high-speed digital-to-analog converter (DAC) with on-chip

voltage reference.

Operating with update rates of up to 200 MSPS, the DAC5662 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 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 DAC5662 has two 12-bit parallel input ports with separate clocks and data latches. For flexibility, the

DAC5662 also supports multiplexed data for each DAC on one port when operating in the interleaved mode.

The DAC5662 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 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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
