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 = 25C, unless otherwise noted.)

The reference voltage for the system uses an MC1403 2.5 V reference IC. The full scale potentiometer can calibrate for a full scale of 199.9 mV or 1.999 V. When switching from 2.0 V to 200 mV operation, RI is also changed, as shown on the diagram. When using RC equal to 300 kW, the clock frequency for the system is about 66 kHz. The resulting conversion time is approximately 250 ms. When the input is overrange, the display flashes on and off. The flashing rate is one-half the conversion rate. This is done by dividing the EOC pulse rate by 2 with 1/2 MC14013B flip-flop and blanking the display using the blanking input of the MC14543B. The display uses an LED display with common anode digit lines driven with an MC14543B decoder and an MC1413 LED driver. The MC1413 contains 7 Darlington transistor drivers and resistors to drive the segments of the display. The digit drive is provided by four MPS-A12 Darlington transistors operating in an emitter-follower configuration. The MC14543B, MC14013B and LED displays are referenced to VEE via Pin 13 of the MC14433. This places the full power supply voltage across the display. The current for the display may be adjusted by the value of the segment resistors shown as 150 W in Figure 8. +5.0 V 0.1 mF MC1403 1 3 0.1 mF 300 k RC 11 10 2 20 k -5.0 V +5.0 V 0.1 mF 2 12 24 23 22 21 20 MC14433 13 7 8 9 14 15 19 18 17 16 5.0 V DS1 DS2 DS3 DS4 5 3 4 8 9 D S Q 13 11 C Q 12 R 14 7 10 -5.0 V +5.0 V 50 mF -5.0 V D C 6 S R Q Q 1 2 MC14013B -5.0 V 51 k +5.0 V -5.0 V -5.0 V 8 0.1 mF 41 2 3 5 16 9 10 11 12 13 14 15 7 MC14543B 7 6 5 4 3 2 1 -5.0 V -5.0 V 10 11 12 13 14 15 16 +5.0 V +5.0 V Segment Resistors 150 W (7) MC1413 VX RI * 3 1 4 5 6 0.1 mF ** 6 Minus Sign 200 W MPS-A12 Plus Sign 110 W Common Anode LED Display fgedc ba 0.1 mF 0.1 mF MPS-A12 (4) * RI = 470 kW for 2.0 V Range RI = 27 kW for 200 mV Range ** Mylar Capacitor Figure 8. 3-1/2-Digit Voltmeter http://onsemi.com 5 MC1403, B ORDERING INFORMATION Device MC1403D MC1403DG MC1403DR2 MC1403DR2G MC1403P1 MC1403P1G MC1403BD MC1403BDG MC1403BDR2 MC1403BP1 MC1403BP1G Package SOIC-8 SOIC-8 (Pb-Free) SOIC-8 SOIC-8 (Pb-Free) PDIP-8 PDIP-8 (Pb-Free) SOIC-8 SOIC-8 (Pb-Free) SOIC-8 PDIP-8-8 PDIP-8-8 (Pb-Free) TA = - 40 to +85C TA = 0 to +70C Operating Temperature Range Shipping 98 Units/Rail 98 Units/Rail 2500 Tape/Reel 2500 Tape/Reel 1000 Units/Rail 1000 Units/Tubes 98 Units/Rail 98 Units/Rail 2500 Tape/Reel 1000 Units/Rail 1000 Units/Rail For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. http://onsemi.com 6 MC1403, B PACKAGE DIMENSIONS PDIP-8 P1 SUFFIX CASE 626-05 ISSUE L NOTES: 1.
