LME49720NA from Texas Instruments, in a PDIP-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 | Output A | output | Audio output A of the first op-amp channel with maximum voltage swing of ±14.1V at 10kΩ load. |
| 2 | InputA- | input | Inverting input of the first op-amp channel, accepting audio signals within common-mode range of (V+)-2.0V to (V-)+2.0V. |
| 3 | InputA+ | input | Non-inverting input of the first op-amp channel, accepting audio signals within common-mode range of (V+)-2.0V to (V-)+2.0V. |
| 4 | V- | power_in | Negative supply voltage pin requiring -2.5V to -17V DC supply for dual-supply operation. |
| 5 | InputB+ | input | Non-inverting input of the second op-amp channel, accepting audio signals within common-mode range of (V+)-2.0V to (V-)+2.0V. |
| 6 | InputB- | input | Inverting input of the second op-amp channel, accepting audio signals within common-mode range of (V+)-2.0V to (V-)+2.0V. |
| 7 | Output B | output | Audio output B of the second op-amp channel with maximum voltage swing of ±14.1V at 10kΩ load. |
| 8 | V+ | power_in | Positive supply voltage pin requiring +2.5V to +17V DC supply for dual-supply operation. |
