FEATURES

DESCRIPTION

Micropower Operation: 250 µA at 5 V AV

Power-On Reset to Min-Scale

16-Bit Monotonic

The DAC8541 is a low-power, single channel, 16-bit,

voltage output DAC. Its on-chip precision output

amplifier allows rail-to-rail voltage swing to be achieved

at the output. The DAC8541 utilizes a 16-bit parallel

interface and features additional powerdown function

pins as well as hardware-enabled, asynchronous DAC

updating and reset capability.

Settling Time: 10 µs to 0.003% FSR

16-Bit Parallel Interface

On-Chip Output Buffer Amplifier With

Rail-to-Rail Operation

The DAC8541 requires an external reference voltage to

set the output range of the DAC. The device

incorporates a power-on-reset circuit that ensures that

the DAC output powers up at min-scale and remains

there until a valid write takes place to the device. In

addition, the DAC8541 contains a power-down feature,

accessed via two hardware pins, that when enabled

reduces the current consumption of the device to

200 nA at 5 V.

Hardware Reset to Min-Scale or Mid-Scale

Double-Buffered Architecture

Asynchronous LDAC Control

Data Readback Support

1.8 V Compatible Digital Interface:

− DV

= 1.8 V−5.5 V

Wide Analog Supply Range:

− AV = 2.7 V−5.5 V

The low power consumption of this device in normal

operation makes it ideally suited for use in portable

battery operated equipment applications. The power

32-Lead 5 mm × 5 mm TQFP Package

APPLICATIONS

consumption is 1.2 mW at AV = 5 V reducing to 1 µW

in power-down mode.

Process Control

The DAC8541 is available in a 32-lead TQFP package

with an operating temperature range of −40°C to 85°C.
