These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during
storage or handling to prevent electrostatic damage to the MOS gates.
The DAC5674 operates from an analog supply voltage of 3.3 V and a digital supply voltage of 1.8 V. The digital
I/Os are 1.8-V and 3.3-V CMOS compatible. Power dissipation is 500 mW at maximum operating conditions.
The DAC5674 provides a nominal full-scale differential current-output of 20 mA, supporting both single-ended
and differential applications. The output current can be directly fed to the load with no additional external output
buffer required. The device 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 latter
configuration is preferred for optimum performance at high output frequencies and update rates.
An accurate on-chip 1.2-V temperature compensated band-gap reference and control amplifier allows the user
to adjust the full-scale output current from 20 mA down to 2 mA. This provides 20-dB gain range control
capabilities. Alternatively, an external reference voltage may be applied for maximum flexibility. The device
features a SLEEP mode, which reduces the standby power to approximately 10 mW, thereby optimizing the
power consumption for the system’s need.
The DAC5674 is available in a 48-pin HTQFP PowerPAD
plastic quad flatpack package. The device is
characterized for operation over the industrial temperature range of 40
°C to 85°C.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
