Maximum ratings are those values beyond which device damage can occur.

Maximum ratings applied to the device are individual stress limit values (not

normal operating conditions) and are not valid simultaneously. If these limits are

exceeded, device functional operation is not implied, damage may occur and

reliability may be affected.

Figure 1. A Reference for Monolithic D/A Converters

Providing the Reference Current

for ON Semiconductor 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

matching the impedance on both inputs of the D/A reference

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.
