SBAS023A – SEPTEMBER 2000 – REVISED JULY 2009
16-BIT DIGITAL-TO-ANALOG CONVERTER
with 16-Bit Bus Interface
1
FEATURES
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.
