QUAD, 12-BIT, LOW-POWER, VOLTAGE OUTPUT,

I²C INTERFACE DIGITAL-TO-ANALOG CONVERTER

FEATURES

DESCRIPTION

•

Micropower Operation: 600 µA at 5 V V_DD

Power-On Reset to Zero

+2.7 V to +5.5 V Analog Power Supply

12-Bit Monotonic

I²C™ Interface Up to 3.4 Mbps

The DAC7574 is a low-power, quad channel, 12-bit

buffered voltage output DAC. Its on-chip precision out-

put amplifier allows rail-to-rail output swing to be

achieved. The DAC7574 utilizes an I²C compatible two

wire serial interface supporting high-speed interface

mode with address support of up to four DAC7574s for

a total of 16 channels on the bus.

•

Data Transmit Capability

On-Chip Output Buffer Amplifier, Rail-to-Rail

Operation

Double-Buffered Input Register

Address Support for up to Four DAC7574s

The DAC7574 uses V_DDand GND to set the output

range of the DAC. The DAC7574 incorporates a

power-on-reset circuit that ensures that the DAC output

powers up at zero volts and remains there until a valid

write takes place to the device. The DAC7574 contains

a power-down feature, accessed via the internal control

device to 200 nA at 5 V.

•

Synchronous Update Support for up to 16

Channels

Operation From -40°C to 105°C

Small 10 Lead MSOP Package

•

The low power consumption of this part in normal

operation makes it ideally suited to portable battery

operated equipment. The power consumption is less

than 3mW at V_DD= 5 V reducing to 1 µW in power-down

mode.

APPLICATIONS

•

Process Control

•

Data Acquisition Systems

Closed-Loop Servo Control

PC Peripherals

The DAC7574 is available in a 10-lead MSOP package.
