The SGM71622R2 family is a 16-bit, low power, 2 channels, buffered voltage-output digital-to-analog converter (DAC).
The SGM71622R2 family has an on-chip 2.5V, 5ppm/℃ internal reference. And it provides the programmable full-scale output voltage ranges of 1.25V (GAIN = ½), 2.5V (GAIN = 1) or 5V (GAIN = 2) with high linearity up to ±0.5LSB (TYP) INL.
The SGM71622R2 family has a flexible serial operation interface which is SPI-compatible. Its operation clock is up to 50MHz.
The SGM71622R2 family contains power-on reset management circuits to make sure that there is a default output voltage. There are two version chips with power-on reset to 0V or mid-scale.
The power consumption is 0.7mA/channel at 5.5V, which is suitable for battery-operated equipment. In power-down mode, it consumes 0.5μA/channel.
The SGM71622R2 family is available in a Green TQFN-3×3-16DL package. It operates over an ambient temperature range of -40℃ to +125℃.
