DIP ICL7107CPL, For Electronics
ICL7107 Pinout Configuration
| Pin Number | Pin Name | Description |
| 1 | Supply voltage (+) | Provides the operating voltage for the IC |
| 2,3,4,5,6,7 and 8 | 7-Segment 4th digit | These pins are connected to the 7-segment display for displaying the once digit of output value. |
| 9,10,11,12,13,14 and 25 | 7-segment 3rd digit | These pins are connected to 7-segment for displaying the tenth digit |
| 15,16,17,18,22,23 and 24 | 7-sement 2nd digit | These pins are connected to 7-segment for displaying the hundredth digit |
| 19 and 20 | 7-segment 1st digit | These pins are connected to 7-segment for displaying the thousandth digit |
| 21 | Ground | Connected to the round of the system |
| 26 | Supply voltage (-) | Provide the negative supply voltage |
| 27 | Signal integrate | Connected to a capacitor |
| 28 and 29 | Auto Zero and buff | Connected to capacitor and resistor network |
| 30 and 31 | Input High and Input Low | The analog voltage that has to be measured is connected here |
| 32 | Common | Connected to ground |
| 33 and 34 | Cref+ and Cref- | Capacitor is connected across these pins for neutralizing fluctuations in reference voltage |
| 35 and 36 | Reference High and Reference Low | Either can supply reference voltage or use internal reference voltage |
| 37 | Test pin | Not used during operation |
| 38, 39 and 40 | OSC1, OSC2, OSC3 | Use RC network top set oscillator frequency |
