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

q SERIAL DIGITAL INTERFACE q VOLTAGE OUTPUT: q �1 LSB INTEGRAL LINEARITY q 16-BIT MONOTONIC OVER TEMPERATURE q PRECISION INTERNAL REFERENCE q LOW NOISE: 120nV/ Hz Including Reference q 16-LEAD PLASTIC AND CERAMIC SKINNY DIP AND PLASTIC SOIC PACKAGES

DESCRIPTION

The is a complete monolithic digital-toanalog converter including a +10V temperature compensated 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 midscale. 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 DAC714 is available in a plastic 0.3" DIP, ceramic 0.3" CERDIP, and wide-body plastic SOIC package. The DAC714P, U, HB, and HC are specified over the to +85�C temperature range while the DAC714HL is 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 �10V output, FSR 20V. (3) Errors externally adjustable to zero. (4) Maximum represents the 3 limit. Not 100% tested for this parameter. (5) For the worst-case Binary Two's Complement code changes: FFFF to 0000H and 0000H to FFFFH. (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)
