+2.7 V to +5.5 V, I²C INTERFACE, VOLTAGE OUTPUT, 12-BIT DIGITAL-TO-ANALOG

CONVERTER

FEATURES

DESCRIPTION

•

Micropower Operation: 140 µA @ 5 V

Power-On Reset to Zero

The DAC7571 is a low-power, single channel, 12-bit

buffered voltage output DAC. Its on-chip precision

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

achieved. The DAC7571 utilizes an I²C compatible

two wire serial interface that operates at clock rates

up to 3.4 Mbps with address support of up to two

DAC7571s on the same data bus.

+2.7-V to +5.5 V-Power Supply

Specified Monotonic by Design

Settling Time: 10 µs to ±0.003%FS

I²C™ Interface up to 3.4 Mbps

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

Operation

Double-Buffered Input Register

Address Support for up to Two DAC7571s

Small 6 Lead SOT Package

The output voltage range of the DAC is set to V_DD

The DAC7571 incorporates a power-on-reset circuit

that ensures that the DAC output powers up at zero

volts and remains there until a valid write to the

•

device takes place. The DAC7571 contains

power-down feature, accessed via the internal control

device to 50 nA at 5 V.

Operation From –40°C to 105°C

APPLICATIONS

The low power consumption of this part in normal

operation makes it ideally suited for portable battery

operated equipment. The power consumption is less

than 0.7 mW at V_DD= 5 V reducing to 1 µW in

power-down mode.
