q HIGH-SPEED 16-BIT PARALLEL DOUBLEBUFFERED INTERFACE q VOLTAGE OUTPUT: 13-, 14-, AND 15-BIT LINEARITY GRADES q 16-BIT MONOTONIC OVER TEMPERATURE (L GRADE) q POWER DISSIPATION: 600mW max q GAIN AND OFFSET ADJUST: Convenient for Auto-Cal D/A Converters q 28-LEAD DIP AND SOIC PACKAGES

DESCRIPTION

is a complete 16-bit resolution D/A converter with 16 bits of monotonicity over temperature. 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, 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 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 DAC712 is packaged 28-pin 0.3" wide plastic DIP and a 28-lead wide-body plastic SOIC. The DAC712P, U, PB, UB, are specified over the to +85�C temperature range and the DAC712PK, UK, PL, UL are specified over the to +70�C range.
