DAC101C081QISDX/NOPB

The DAC101C081 device is a 10-bit, single-channel, voltage-output digital-to-analog converter (DAC) that operates from a power supply ranging from 2.7V to 5.5V. The output amplifier supports rail-to-rail output swing and has a settling time of 6μs. The DAC101C081 uses the power supply as the reference to provide the widest dynamic output range and typically consumes only 132μA of current when operating at 5.0V. The device is available in 6-pin small outline transistor (SOT) and wafer-level small outline no-lead (WSON) packages and offers three address options (selectable via pins). The DAC101C085 is an alternative product that offers nine I2C addressing options and uses an external reference. The device is available in an 8-pin very thin shrink small outline package (VSSOP) and has the same performance and settling time as the DAC101C081. The DAC101C081 and DAC101C085 feature a two-wire I2C-compatible serial interface that supports all three speed modes, including the high-speed mode (3.4MHz). With the external address selection pins, up to three DAC101C081 or nine DAC101C085 devices can be connected on each two-wire bus. In addition, pin-compatible alternatives to the DAC101C081 are available, offering more address options. Both the DAC101C081 and DAC101C085 have a 16-bit register for controlling the operating mode, power-saving conditions, and output voltage. The power-on reset circuit ensures that the DAC output voltage is 0V at power-up. The power-saving feature can reduce the device's power consumption to less than 1 microwatt. The low power consumption and small package make these two DACs an excellent choice for battery-powered devices. Each DAC operates over the extended industrial temperature range of -40°C to +125°C. The families to which the DAC101C081 and DAC101C085 belong also offer pin-compatible DACs with 12-bit and 8-bit resolutions. The 12-bit DACs are the DAC121C081 and DAC121C085, respectively. The 8-bit DACs are the DAC081C081 and DAC081C085, respectively.
