DAC121C081/ DAC121C085

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

I²C-Compatible Interface

General Description

The DAC121C081 is a 12-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 8.5usec settling time. The DAC121C081

uses the supply voltage as the reference to provide the widest

dynamic output range and typically consumes 132uA 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 12-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 6-pin TSOT and LLP Packages

As an alternative, the DAC121C085 provides nine I²C ad-

dressing options and uses an external reference. It has the

same performance and settling time as the DAC121C081. It

is available in an 8-lead MSOP.

The DAC121C081 and DAC121C085 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 DAC121C081 or nine

DAC121C085 devices per 2-wire bus. Pin compatible alter-

natives to the DAC121C081 are available that provide addi-

tional address options.

Power Down

The DAC121C081 and DAC121C085 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 DAC121C081 and DAC121C085 are each part of a fam-

ily of pin compatible DACs that also provide 8 and 10 bit

resolution. For 8-bit DACs see the DAC081C081 and

DAC081C085. For 10-bit DACs see the DAC101C081 and

DAC101C085.

Pin-Compatible Alternatives

All devices are fully pin and function compatible.
