DESCRIPTION
The DAC712 is a complete 16-bit resolution
digital-to-analog (D/A) converter with 16 bits of
monotonicity over temperature.
The DAC712 has a precision +10V
temperature-compensated voltage reference, ±10V
output amplifier, and 16-bit port bus interface.
The digital interface is fast, 60ns minimum write pulse
width, double-buffered, and has a CLEAR function
that resets the analog output to bipolar zero.
GAIN and OFFSET adjustment inputs are arranged
so that they can be easily trimmed by external D/A
converters as well as by potentiometers.
The DAC712 is available in two linearity error
performance grades: ±4LSB and ±2LSB, and three
differential linearity grades: ±4LSB, ±2LSB, and
±1LSB. The DAC712 is specified at power-supply
voltages of ±12V and ±15V.
The DAC712 is packaged in a 28-pin, 0.3" wide
plastic DIP and in a 28-lead, wide-body plastic SOIC.
The DAC712P, U, PB, and UB are specified over the
–40°C to +85°C temperature range and the
DAC712PK, UK, PL, and UL are specified over the
0°C to +70°C range.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
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 its published specifications.
