Component qualification in accordance with JEDEC and

industry standards to ensure reliable operation over an

extended temperature range. This includes, but is not limited

to, Highly Accelerated Stress Test (HAST) or biased 85/85,

temperature cycle, autoclave or unbiased HAST,

electromigration, bond intermetallic life, and mold compound

life. Such qualification testing should not be viewed as

justifying use of this component beyond specified

performance and environmental limits.

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.
