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.

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 monolithic 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. ELECTRICAL CHARACTERISTICS (Vin = 15 V, TA = 25°C, unless otherwise noted.)
