The SGM5349A-16 is a low power, 8 channels, 16-bit, buffered voltage-output DAC. It operates from a single 2.7V to 5.5V supply and the monotonicity is guaranteed by design. The SGM5349A-16 has no internal voltage reference, and the full-scale output range is VREF.

The part incorporates a power-on reset circuit that ensures that the DAC output powers up to 0V and remains powered up at this level until a valid write takes place. The part contains a power-down feature that reduces the current consumption of the device to 1μA at 5.5V and provides software-selectable output loads while in power-down mode for any or all DAC channels. The outputs can be updated simultaneously using the LDAC function, with the added functionality of user- selectable DAC channels to simultaneously update. There is also an asynchronous CLR that updates DAC to a user-programmable code: zero scale, midscale, or full scale.
