PRECISION LOW VOLTAGE

REFERENCE

A precision band–gap voltage reference designed for critical

instrumentation and D/A converter applications. This unit is designed to work

with D/A converters, up to 12 bits in accuracy, or as a reference for power

supply applications.

Providing the Reference Current

for Motorola Monolithic D/A Converters

The MC1403 makes an ideal reference for many mono-

lithic D/A converters, requiring a stable current reference of

nominally 2.0 mA. This can be easily obtained from the

MC1403 with the addition of a series resistor, R1. A variable

resistor, R2, is recommended to provide means for full–

scale adjust on the D/A converter.

The resistor R3 improves temperature performance by

matchingtheimpedanceonbothinputsoftheD/Areference

amplifier. The capacitor decouples any noise present on the

reference line. It is essential if the D/A converter is located

any appreciable distance from the reference.

A single MC1403 reference can provide the required

current input for up to five of the monolithic D/A converters.
