DAC716

16-Bit DIGITAL-TO-ANALOG CONVERTER

with Serial Data Interface

DESCRIPTION

The DAC716 is a complete monolithic D/A converter
including a +10V temperature compensated voltage
reference, current-to-voltage amplifier, a high-speed
synchronous serial interface, a serial output which
allows cascading multiple converters, and an asyn­chronous clear function which immediately sets the
output voltage to zero.

The output voltage range is 0 to +10V while operating
from ±12V to ±15V supplies, and the gain and bipolar
offset adjustments are designed so that they can be set
via external potentiometers or external D/A convert­ers. The output amplifier is protected against short­circuiting to ground.

The 16-pin DAC716 is available in a plastic 0.3" DIP
and a wide-body plastic SOIC package. The DAC716P,
U, PB, and UB are specified over the –40°C to +85°C
range while the DAC716UK and PK are specified
over the 0°C to +70°C range.

PIN CONFIGURATION

ELECTROSTATIC
DISCHARGE SENSITIVITY

Electrostatic discharge can cause damage ranging from per­formance degradation to complete device failure. Burr­Brown Corporation recommends that all integrated circuits
be handled and stored using appropriate ESD protection
methods.

ESD damage can range from subtle performance degrada­tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet
published specifications.
