DESCRIPTION
DAC712 is a complete 16-bit resolution D/A converter
with 16 bits of monotonicity over temperature.
DAC712 has a precision +10V temperature compen-
sated voltage reference,
±10V
output amplifier and
16-bit port bus interface.
The digital interface is fast, 60ns minimum write pulse
width, is 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.
DAC712 is available in two linearity error perfor-
mance grades:
±4LSB
and
±2LSB
and three differen-
tial linearity grades:
±4LSB, ±2LSB,
and
±1LSB.
The
DAC712 is specified at power supply voltages of
±12V
and
±15V.
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, UB, are specified over the –40°C to
+85°C temperature range and the DAC712PK, UK,
PL, UL are specified over the 0°C to +70°C range.
