DAC7614

Quad, Serial Input, 12-Bit, Voltage Output

DIGITAL-TO-ANALOG CONVERTER

FEATURES

● LOW POWER: 20mW

● UNIPOLAR OR BIPOLAR OPERATION

● SETTLING TIME: 10µs to 0.012%

● 12-BIT LINEARITY AND MONOTONICITY:

–40°C to +85°C

● USER SELECTABLE RESET TO MID-

SCALE OR ZERO-SCALE

● SECOND-SOURCE for DAC8420

● SMALL 20-LEAD SSOP PACKAGE

DESCRIPTION

The DAC7614 is a quad, serial input, 12-bit, voltage output digital-to-analog converter (DAC) with guaranteed 12-bit monotonic performance over the –40°C to +85°C temperature range. An asynchronous reset clears all registers to either mid-scale (800H) or zeroscale (000H), selectable via the RESETSEL pin. The device can be powered from a single +5V supply or from dual +5V and –5V supplies.

APPLICATIONS

● ATE PIN ELECTRONICS

● PROCESS CONTROL

● CLOSED-LOOP SERVO-CONTROL

● MOTOR CONTROL

● DATA ACQUISITION SYSTEMS

Low power and small size makes the DAC7614 ideal for process control, data acquisition systems, and closed-loop servo-control. The device is available in 16-pin plastic DIP, 16-lead SOIC, or 20-lead SSOP packages, and is guaranteed over the –40°C to +85°C temperature range.

ELECTROSTATIC DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with

+ 0.3V

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

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 its published specifications.
