The DAC5672A device is a monolithic, dual-channel, 14-bit, high-speed DAC with on-chipvoltage reference.

Operating with update rates of up to 275 MSPS, the DAC5672A offers exceptional dynamicperformance, tight-gain, and offset matching characteristics that make the device well-suited inI/Q baseband or direct IF communication applications.

Each DAC has a high-impedance, differential-current output, suitable for single-ended ordifferential analog-output configurations. External resistors allow scaling the full-scale outputcurrent for each DAC separately or together, typically between 2 mA and 20 mA. An accurate on-chipvoltage reference is temperature-compensated and delivers a stable 1.2-V reference voltage.Optionally, an external reference may be used.

The DAC5672A has two, 14-bit, parallel input ports with separate clocks and data latches.For flexibility, the DAC5672A supports multiplexed data for each DAC on one port when operating inthe interleaved mode.

The DAC5672A is specifically designed for a differential transformer-coupled output witha 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.

The DAC5672A is available in a 48-pin TQFP package. Pin compatibility between familymembers provides 12-bit (DAC5662) and 14-bit (DAC5672A) resolutions. Furthermore, the DAC5672A ispin compatible to the DAC2904 and AD9767 dual DACs. The device is characterized for operation overthe industrial temperature range of –40°C to 85°C.
