DAC101C081/ DAC101C085

10-Bit Micro Power Digital-to-Analog Converter with an

I²C-Compatible Interface

General Description

The DAC101C081 is a 10-bit, single channel, voltage-output

digital-to-analog converter (DAC) that operates from a +2.7V

to 5.5V supply. The output amplifier allows rail-to-rail output

swing and has an 6µsec settling time. The DAC101C081 uses

the supply voltage as the reference to provide the widest dy-

namic output range and typically consumes 132µA while

operating at 5.0V. It is available in 6-lead TSOT and LLP

packages and provides three address options (pin se-

lectable).

Features

Guaranteed Monotonicity to 10-bits

■

Low Power Operation: 156 µA max @ 3.3V

Extended power supply range (+2.7V to +5.5V)

I²C-Compatible 2-wire Interface which supports standard

(100kHz), fast (400kHz), and high speed (3.4MHz) modes

Rail-to-Rail Voltage Output

■

Very Small Package

As an alternative, the DAC101C085 provides nine I²C ad-

dressing options and uses an external reference. It has the

same performance and settling time as the DAC101C081. It

is available in an 8-lead MSOP.

The DAC101C081 and DAC101C085 use a 2-wire, I²C-com-

patible serial interface that operates in all three speed modes,

including high speed mode (3.4MHz). An external address

selection pin allows up to three DAC101C081 or nine

DAC101C085 devices per 2-wire bus. Pin compatible alter-

natives to the DAC101C081 are available that provide addi-

tional address options.

Power Down

The DAC101C081 and DAC101C085 each have a 16-bit reg-

ister that controls the mode of operation, the power-down

condition, and the output voltage. A power-on reset circuit

ensures that the DAC output powers up to zero volts. A power-

down feature reduces power consumption to less than a

microWatt. Their low power consumption and small packages

make these DACs an excellent choice for use in battery op-

erated equipment. Each DAC operates over the extended

industrial temperature range of −40°C to +125°C.

■

The DAC101C081 and DAC101C085 are each part of a fam-

ily of pin compatible DACs that also provide 12 and 8 bit

resolution. For 12-bit DACs see the DAC121C081 and

DAC121C085. For 8-bit DACs see the DAC081C081 and

DAC081C085.

Pin-Compatible Alternatives

All devices are fully pin and function compatible.
