KA22241G-S14-R from UTC Unisonic Tech, in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Channel 1 equalizer amplifier output. Drives external NF/time-constant network back to NF1 (pin 11) for the NAB playback equalization. |
| 2 | GND | power_in | Signal / power ground reference for the device. |
| 3 | NC | unconnected | No internal connection. Leave floating or tie to ground per PCB practice. |
| 4 | ALC | passive | ALC (Automatic Level Control) time-constant pin. External capacitor to GND (e.g. 22 μF) sets the ALC attack/release response; also connects the mute/ALC network shared between channel 1 and channel 2. |
| 5 | VCC | power_in | Positive supply voltage. Typical VCC = 7 V; absolute maximum 16 V. Bypass locally with a decoupling capacitor (e.g. 330 μF + ceramic). |
| 6 | NC | unconnected | No internal connection. |
| 7 | OUT2 | output | Channel 2 equalizer amplifier output. Drives external NF/time-constant network back to NF2 (pin 10) for the NAB playback equalization. |
| 8 | NC | unconnected | No internal connection. |
| 9 | IN2 | input | Channel 2 equalizer amplifier inverting input. No input coupling capacitor is required (internal DC biasing). Typical input resistance ~25 kΩ. |
| 10 | NF2 | passive | Channel 2 negative-feedback / NAB time-constant network node. External R (e.g. 15 kΩ) + C to GND sets closed-loop gain (~48 dB typ) and equalization; playback replaces R with the 4.3 kΩ / 120 kΩ // 0.027 μF NAB network back to OUT2. |
| 11 | NF1 | passive | Channel 1 negative-feedback / NAB time-constant network node. External R (e.g. 15 kΩ) + C to GND sets closed-loop gain (~48 dB typ) and equalization; playback replaces R with the 4.3 kΩ / 120 kΩ // 0.027 μF NAB network back to OUT1. |
| 12 | NC | unconnected | No internal connection. |
| 13 | IN1 | input | Channel 1 equalizer amplifier inverting input. No input coupling capacitor is required (internal DC biasing). Typical input resistance ~25 kΩ. |
| 14 | NC | unconnected | No internal connection. |
