DAC7741

SBAS248B – DECEMBER 2001 – REVISED AUGUST 2007

16-Bit, Single Channel

DIGITAL-TO-ANALOG CONVERTER

With Internal Reference and Parallel Interface

DESCRIPTION

FEATURES

ꢀ LOW POWER: 150mW MAXIMUM

The DAC7741 is a 16-bit Digital-to-Analog Converter (DAC)

which provides 16 bits of monotonic performance over the

specified operating temperature range and offers a +10V,

low-drift internal reference. Designed for automatic test equip-

ment and industrial process control applications, the DAC7741

output swing can be configured in a ±10V, ±5V, or +10V

range. The flexibility of the output configuration allows the

DAC7741 to provide both unipolar and bipolar operation by

pin strapping. The DAC7741 includes a high-speed output

amplifier with a maximum settling time of 5µs to ±0.003%

FSR for a 20V full-scale change and only consumes 100mW

(typical) of power.

ꢀ +10V INTERNAL REFERENCE

ꢀ UNIPOLAR OR BIPOLAR OPERATION

ꢀ SETTLING TIME: 5µs to ±0.003% FSR

ꢀ 16-BIT MONOTONICITY, –40°C TO +85°C

ꢀ ±10V, ±5V OR +10V CONFIGURABLE VOLTAGE

OUTPUT

ꢀ RESET TO MIN-SCALE OR MID-SCALE

ꢀ DOUBLE-BUFFERED DATA INPUT

ꢀ INPUT REGISTER DATA READBACK

ꢀ SMALL LQFP-48 PACKAGE

The DAC7741 features a standard 16-bit parallel interface with

double buffering to allow asynchronous updates of the analog

output and data read-back to support data integrity verification

prior to an update. A user-programmable reset control allows

the DAC output to reset to min-scale (0000_H) or mid-scale

(8000_H) overriding the DAC register values. The DAC7741 is

available in a LQFP-48 package and four performance grades

specified to operate from 0°C to +70°C and –40°C to +85°C.
