DESCRIPTION  
The DAC5672 is a monolithic, dual-channel, 14-bit, high-speed DAC with on-chip voltage reference.  
Operating with update rates of up to 275 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-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.  
The DAC5672 is available in a 48-pin 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 industrial temperature range of -40°C to  
85°C.
