MC14433 3% DIGIT A/D CONVERTER The MC14433 is a high-performance, low-power, 3% digit A/D converter combining both linear CMOS and digital CMOS circuits on a single monolithic CMOS LSI IC. The MC14433 is designed to minimize use of external components. With two (LOW-POWER COMPLEMENTARY MOS) external resistors and two external capacitors, the system forms a dual-slope A/D converter with automatic zero correction and automatic polarity. The MC14433 is ratiometric and may be used over a full-scale range of 1.999 3% DIGIT A/D CONVERTER volts or 199.9 millivolts. Systems using the MC14433 may operate over a wide range of power supply voltages for ease of use with batteries, or with standard 5 valt supplies. The output drive conforms with standard B-Series CMOS spec- ifications and can drive a low-power Schottky TTL ioad. The high-impedance MOS inputs allow applications in current and resistance meters as well as voltmeters. In addition ta DVM/DPM app

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 in Figure 8. An example of a 3-1/2-digit voltmeter using the MC14433 is shown in the circuit diagram of Figure 8. 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 k, 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.
