illustrate
DAC101C081 is a 10-bit, single-channel, voltage-output digital-to-analog converter (DAC) that operates from a +2.7 V to 5.5V supply. The output amplifier allows rail-to-rail output swing and 6μsec resolution time. DAC101C081 supply voltage used as a reference provides the widest dynamic output range, with a typical power consumption of 132μA and 5.0V operation. It is available in 6-pin TSOT and LLP packages and is available in three address options (pin selectable).
As an alternative, DAC101C085 offers 9 I 2 Comet processing options and use of external references. It has the same performance and DAC101C081 of stabilization time. It is on an 8-pin MSOP.
DAC101C081 and DAC101C085 use 2 wires, me 2 C-compatible serial interface that operates in all three speed modes, including high-speed mode (3.4MHz). The external address selection pin allows DAC101C081 or 9 DAC101C085 per 2-wire bus device. DAC101C081 is a pin-compatible alternative that can provide additional address options.
DAC101C081 and DAC101C085 each have a 16-bit register that controls the operating mode, power-down conditions, and output voltage. Power-on reset circuit to ensure the DAC's output power up to zero volts. The power loss function reduces the power consumption to less than one microwatt. Their low power consumption and small package make these DACs a great choice for using battery-powered devices. Each DAC operates over an extended industrial temperature range of -40°C to +125°C
DAC101C081 and DAC101C085 are pin-compatible DACs that also offer 12 and 8-bit resolution for every part of the family. The 12-bit DAC sees DAC121C081 and DAC121C085. The 8-bit DAC sees DAC081C081 and DAC081C085.
