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.
