LM4880MX from Texas Instruments, in a SOIC-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 | OUT A | output | Channel A amplifier output, AC-coupled to the load through output coupling capacitor Co. |
| 2 | IN A | input | Channel A inverting input, with gain set by Ri and RF and coupled through input capacitor Ci. |
| 3 | BYPASS | passive | Half-supply bypass pin that takes capacitor CB (1.0 µF or larger recommended) for PSRR and turn-on click and pop performance. |
| 4 | GND | power_in | Ground pin, the reference for all voltages. |
| 5 | SHUTDOWN | input | Shutdown control: a logic high (trigger point typically half supply) turns the amplifier off, and the pin must be tied to a definite voltage, not left floating. |
| 6 | IN B | input | Channel B inverting input, with gain set by Ri and RF and coupled through input capacitor Ci. |
| 7 | OUT B | output | Channel B amplifier output, AC-coupled to the load through output coupling capacitor Co. |
| 8 | VDD | power_in | Positive supply, 2.7V to 5.5V operating (6.0V absolute maximum), with a supply bypass capacitor placed close to the pin. |
