DAC121C081/ DAC121C085 12-Bit Micro Power Digital-to-Analog Converter with an I²C-

Compatible Interface

Check for Samples: DAC121C081, DAC121C085

FEATURES

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 8.5µsec

settling time. The DAC121C081 uses the supply

voltage as the reference to provide the widest

dynamic output range and typically consumes 132µA

while operating at 5.0V. It is available in 6-lead SOT

and WSON packages and provides three address

options (pin selectable).

As an alternative, the DAC121C085 provides nine I²C

addressing options and uses an external reference. It

has the same performance and settling time as the

DAC121C081. It is available in an 8-lead VSSOP.

•

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 Package

APPLICATIONS

•

Industrial Process Control

Portable Instruments

The DAC121C081 and DAC121C085 use a 2-wire,

I²C-compatible 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 alternatives to the

DAC121C081 are available that provide additional

address options.

KEY SPECIFICATIONS

•

Resolution: 12 bits

The DAC121C081 and DAC121C085 each have a

16-bit register 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 operated equipment. Each DAC operates over

the extended industrial temperature range of −40°C

to +125°C.

INL: ±8 LSB (max)

DNL: +0.6 / -0.5 LSB (max)

Settling Time: 8.5 µs (max)

Zero Code Error: +10 mV (max)

Full-Scale Error: −0.7 %FS (max)

Supply Power

–

Normal: 380 µW (3V) / 730 µW (5V) typ

Power Down: 0.5 µW (3V) / 0.9 µW (5V) typ

The DAC121C081 and DAC121C085 are each part of

a family 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.
