PT2308-S from PTC Princeton Tech, in a SOIC-8. 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 | Output pin 1 - Class AB analog audio output of the first (left) channel headphone driver. Drives typical 10 kΩ headphone load via an AC-coupling capacitor (100 µF in the reference circuit). |
| 2 | IN1- | input | Inverting input pin of channel 1 op-amp. Used with the 3.9 kΩ feedback network to set channel-1 gain in the reference application circuit. |
| 3 | IN1+ | input | Non-inverting input pin of channel 1 op-amp. Biased to VREF in the reference application circuit. |
| 4 | VSS | power_in | Negative power supply / ground return for the IC. Connect to system ground (or negative rail in split-supply operation). |
| 5 | IN2+ | input | Non-inverting input pin of channel 2 op-amp. Biased to VREF in the reference application circuit. |
| 6 | IN2- | input | Inverting input pin of channel 2 op-amp. Used with the 3.9 kΩ feedback network to set channel-2 gain in the reference application circuit. |
| 7 | OUT2 | output | Output pin 2 - Class AB analog audio output of the second (right) channel headphone driver. Drives typical 10 kΩ headphone load via an AC-coupling capacitor (100 µF in the reference circuit). |
| 8 | VDD | power_in | Positive power supply pin. Decoupled to VSS in the reference application circuit. Powers both channel op-amps. |
