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 -0°C to +85°C temperature range and the DAC712PK, UK, PL, and UL are specified over the 0°C to +70°C range.
