ICL7650SCPA-1Z from RENESAS, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CEXTA | passive | Null/storage capacitor connection A; a 0.1 µF low-dielectric-absorption capacitor (mylar or polypropylene preferred) connects here with its return at CRETN. |
| 2 | -IN | input | Inverting input; the input voltage must stay within the absolute maximum range of (V+ + 0.3 V) to (V- - 0.3 V), and drive current should be limited to under 1 mA to avoid latchup. |
| 3 | +IN | input | Non-inverting input; the common mode voltage range is -5 V to +3.5 V over 0 to +70 °C, and the same input voltage and latchup limits apply. |
| 4 | V- | power_in | Negative supply rail; the operating supply range V+ to V- is 4.5 V to 16 V, and the amplifier supplies should be established at the same time as or before any input signal is applied. |
| 5 | CRETN | passive | Common return for the two null capacitors; the CEXTA/CEXTB common connection should be made directly by a separate wire or trace, and any outside foil should be connected to CRETN. |
| 6 | OUTPUT | output | Amplifier output with a typical output impedance of about 18k; it guarantees at least 2.3 mA source and 20 mA sink current over 0 to +70 °C, and a short-circuit duration of indefinite is permitted. |
| 7 | V+ | power_in | Positive supply rail; the operating supply range V+ to V- is 4.5 V to 16 V, and the absolute maximum supply voltage (V+ to V-) is 18 V. |
| 8 | CEXTB | passive | Null/storage capacitor connection B; a 0.1 µF low-dielectric-absorption capacitor connects here, paired with CEXTA and returned to CRETN. |
