A Reference for Monolithic D/A Converters + 5.0 V 1 MC1403 3 2 2.5 V Full Scale Adjust 500 Ω 1.0 k R1 R2 Reference Amplifier IRef *0.1 µF C1 Providing the Reference Current for Motorola 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. 1.2 k R3 * Caution: System stability may be affected if output capacitance * exceeds 1.0 µF. Using higher capacitance values is not * recommended and should be carefully considered. 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. © Motorola, Inc. 1996 MOTOROLA ANALOG IC DEVICE DATA Monolithic D/A Converter Rev 1 1
