Description

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

The DAC5672A 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 DAC5672A is available in a 48-pin TQFP package. Pin compatibility between family members provides 12-bit (DAC5662) and 14-bit (DAC5672A) resolution. Furthermore, the DAC5672A 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.
