●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.
