16-Bit DIGITAL-TO-ANALOG CONVERTER with Serial Data Interface

q SERIAL DIGITAL INTERFACE q VOLTAGE OUTPUT: q �2 LSB INTEGRAL LINEARITY q PRECISION INTERNAL REFERENCE q LOW NOISE: 120nV/ Hz Including Reference q 16-LEAD PLASTIC SKINNY DIP AND PLASTIC SOIC PACKAGES

DESCRIPTION

The is a complete monolithic D/A converter including a +10V temperature compensated voltage reference, current-to-voltage amplifier, a high-speed synchronous serial interface, a serial output which allows cascading multiple converters, and an asynchronous clear function which immediately sets the output voltage to zero. The output voltage range to +10V while operating from to �15V supplies, and 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 shortcircuiting to ground. The DAC716 is available in a plastic 0.3" DIP and a wide-body plastic SOIC package. The DAC716P, U, PB, and UB are specified over the to +85�C range while the DAC716UK and PK 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 the 3 limit. Not 100% tested for this parameter. (5) For the worst-case Straight Binary code changes: to 8000 and 7FFF. (6) During power supply turn on, the transient supply current may approach 3x the maximum quiescent specification. (7) Typical (i.e. rated) supply voltages times maximum currents.

Electrostatic discharge can cause damage ranging from performance degradation to complete device failure. BurrBrown 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. ABSOLUTE MAXIMUM RATINGS(1)
