ICL7650N-14
HGSEMI · Operational Amplifier · DIP-14
ICL7650N-14 from HGSEMI, in a DIP-14. 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 | CEXTB | passive | External nulling/storage capacitor connection B, with the other capacitor terminal to CRETN; 0.1uF for the internal clock. |
| 2 | CEXTA | passive | External nulling/storage capacitor connection A, with the other capacitor terminal to CRETN; 0.1uF for the internal clock. |
| 3 | NC (GUARD) | unconnected | No connect pin next to the inputs, usable for guarding to reduce input leakage. |
| 4 | -IN | input | Inverting input of the amplifier. |
| 5 | +IN | input | Non-inverting input of the amplifier. |
| 6 | NC (GUARD) | unconnected | No connect pin next to the inputs, usable for guarding to reduce input leakage. |
| 7 | V- | power_in | Negative supply; supply range V+ to V- is 4.5V min to 16V max (absolute maximum 18V). |
| 8 | CRETN | passive | Common return for the two null/storage capacitors, connected directly by a separate wire or PC trace. |
| 9 | OUT CLAMP | output | Output clamp; tie to the inverting input to reduce overload recovery time. |
| 10 | OUTPUT | output | Amplifier output, with a 10kohm load for full swing and indefinite short-circuit duration. |
| 11 | V+ | power_in | Positive supply; supply range V+ to V- is 4.5V min to 16V max (absolute maximum 18V). |
| 12 | INT CLK OUT | output | Internal clock oscillator output on the 14-pin version. |
| 13 | EXT CLK IN | input | External clock input; leave open (with pin 14) for the internal chopping frequency of 250Hz typical. |
| 14 | INT/EXT | input | Selects internal or external clock; leave open (with pin 13) for the internal chopping frequency of 250Hz typical. |
