GENERAL DEscriptION

The SGM5351-16 is a low power, single channel, 16-bit, voltage-output DAC. It operates from a 2.7V to 5.5V supply and the monotonicity is guaranteed by design.

The SGM5351-16 sets the output range by using an external reference voltage. It incorporates a power-on reset circuit that ensures the DAC output powers to 0V and remains powered up at this level until a valid write takes place. The SGM5351-16 provides a power-down mode accessed via the serial interface that reduces the current consumption of the device to 450nA (TYP) at 5.5V. The SGM5351-16 consumes 0.27mW (TYP) at 2.7V in normal mode, which reduces to less than 1μW in power‑down mode, the low power consumption in normal mode is very suitable for portable battery- operated equipment.

The SGM5351-16 uses a 3-wire serial interface which can be operated at clock rates to 30MHz and is compatible with standard SPI interface.

The SGM5351-16 is available in a Green MSOP-8 package. It operates over an ambient temperature range of -40℃ to +125℃.
