LME49720NA

Texas Instruments · Audio Amplifiers · PDIP-8

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.
