The DAC101C081 is a 10-bit, single-channel, voltage-output digital-to-analog converter (DAC) that operates from a +2.7 V to 5.5 V supply.
The output amplifier allows rail-to-rail output swing and 6μsec resolution time.
The DAC101C081 uses a supply voltage as a reference to provide the widest dynamic output range, typically consuming 132μA while operating at 5.0V.
It is available in 6-pin TSOT and LLP packages and offers three address options (pin selectable).
As an alternative, the DAC101C085 offers 9 I

Comet treatment options and use external references.
It has the same performance and settling time as the DAC101C081.
It is in an 8-pin MSOP.
The DAC101C081 and DAC101C085 use 2 wires, i
2
C-compatible serial interface that operates in all three speed modes, including high-speed mode (3.4MHz).
An external address select pin allows the DAC101C081 or 9 DAC101C085 to be used every 2-wire bus device.
The DAC101C081 is a pin-compatible alternative that can provide additional address options.
The DAC101C081 and DAC101C085 each have a 16-bit register that controls the operating mode, power-down conditions, and output voltage.
A power-on reset circuit ensures that the DAC output power is up to zero volts.
Power-down function reduces power consumption by less than one microwatt.
Their low power consumption and small package make these DACs an excellent choice for battery-powered devices.
Each DAC operates over an extended industrial temperature range of -40°C to +125°C
The DAC101C081 and DAC101C085 are pin-compatible DACs that also offer each part of the family with 12- and 8-bit resolution.
The 12-bit DAC sees the DAC121C081 and DAC121C085.
The 8-bit DAC sees DAC081C081 and DAC081C085.
