DAC6571

SLAS406B – DECEMBER 2003 – REVISED AUGUST 2005

10-BIT DIGITAL-TO-ANALOG CONVERTER

•

Micropower Operation: 125

µA @ 3 V

The DAC6571 is a low-power, single-channel, 10-bit

•

Fast Update Rate: 188 kSPS

buffered voltage output digital-to-analog converter

(DAC). Its on-chip precision output amplifier allows

•

Power-On Reset to Zero

rail-to-rail output swing to be achieved. The DAC6571

•

+2.7-V to +5.5-V Power Supply

•

Specified Monotonic by Design

that operates at clock rates up to 3.4 MBPS with

•

address support of up to two DAC6571s on the same

data bus.

•

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

Operation

•

Double-Buffered Input Register

The DAC6571 incorporates a power-on-reset circuit

•

Address Support for up to Two DAC6571s

that ensures that the DAC output powers up at zero

volts and remains there until a valid write to the

•

Small SOT23-6 Package

device

takes

place.

The

DAC6571

contains

a

•

Operation From –40

°C to +105°C

power-down feature, accessed via the internal control

register, that reduces the current consumption of the

device to 50 nA at 5 V.

•

Process Control

The low power consumption of this part in normal

are

12/10/8-bit,

DAC7574/6574/5574 and DAC7573/6573/5573 are

DACs.
