(1) 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 DAC5672 is a monolithic, dual-channel, 14-bit, high-speed digital-to-analog converter (DAC) with on-chip voltage reference.
Operating with update rates of up to 200 MSPS, the DAC5672 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 DAC5672 has two 14-bit parallel input ports with separate clocks and data latches. For flexibility, the DAC5672 also supports multiplexed data for each DAC on one port when operating in the interleaved mode.
The DAC5672 has been specifically designed for a differential transformer-coupled output with a 50-
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 DAC5672 is available in a 48-pin thin quad flat pack (TQFP) package. Pin compatibility between family members provides 12-bit (DAC5662) and 14-bit (DAC5672) resolution. Furthermore, the DAC5672 is pin compatible to the DAC2904 and AD9767 dual DACs. The device is characterized for operation over the military temperature range of -55°C to 125°C.
