q HIGH-SPEED 16-BIT PARALLEL DOUBLEBUFFERED INTERFACE q VOLTAGE OUTPUT: 14-, 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

The is a complete monolithic digital-toanalog converter including a +10V temperature compensated reference, current-to-voltage amplifier, 16-bit parallel interface that is double buffered, and an asynchronous clear function which immediately sets the output voltage to one-half of full-scale. The output voltage range to +10V while operating from or �15V supplies. The gain and bipolar offset adjustments are designed so that they can be set via external potentiometers or external D/A converters. The output amplifier is protected against short circuit to ground. The DAC715 is available a 0.3" plastic DIP and wide-body plastic SOIC package. The DAC715P, U, PB, and UB are specified over the to +85�C temperature range while the DAC715PK, UK, PL, and UL are specified over the to +70�C range.

NOTES: (1) Digital inputs are TTL and +5V CMOS compatible over the specification temperature range. (2) FSR means Full Scale Range. For example, for to +10V output, FSR 10V. (3) Errors externally adjustable to zero. (4) Maximum represents greater than the 3 limit. Not 100% tested for this parameter. (5) For the worst case code changes: FFFFH to 0000H and 0000H to FFFFH. These are Binary Two's Complement (BTC) codes. (6) Typical supply voltages times maximum currents.

Electrostatic discharge can cause damage ranging from performance degradation to complete device failure. Burr-Brown Corporation recommends that all integrated circuits be handled and stored using appropriate ESD protection methods. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet published specifications.

BURR-BROWN assumes no responsibility for the use of this information, and all use of such information shall be entirely at the user's own risk. Prices and specifications are subject to change without notice. No patent rights or licenses to any of the circuits described herein are implied or granted to any third party.
