The 12 data bits are double buffered so that the output can be updated asynchronously using the LDAC pin. During normal operation, the device dissipates 8 mW at a 5-V supply and 4.3 mW at a 3-V supply. The power consumption can be lowered to 50 nW by setting the DAC to power-down mode. The output voltage is buffered by a ×2 gain rail-to-rail amplifier, which features a Class A output stage to improve stability and reduce settling time.
