| 2 | IN1− | Input | Op-amp A inverting input |
| 3 | IN1+ | Input | Op-amp A non-inverting input |
| 4 | V− · VCC− | GND | Negative supply |
| 5 | IN2+ | Input | Op-amp B non-inverting input |
| 6 | IN2− | Input | Op-amp B inverting input |
| 7 | OUT2 | Output | Op-amp B output |
| 8 | V+ · VCC+ | Power | Positive supply (±3 to ±18V) |
How to read the TL072 pinout
- 01
Find pin 1
One end of the chip has a half-circle notch or a dot; with the notch facing up, the top-left pin is pin 1.
- 02
Count counter-clockwise
Count counter-clockwise from pin 1: go down the left side first, then up the right side from the bottom.
- 03
Check the table below
Look up each pin's function by number in the table below; power/ground are color-coded, and alternate-function signals are in parentheses.
Frequently asked questions
Do the TL072 and LM358 have the same pinout?
Same pin layout (standard 8-pin dual op-amp). The TL072 is JFET-input with low noise and high bandwidth, suiting audio; the LM358 is cheap and its input can reach ground on a single supply.
What's the difference between the TL072 and TL082?
Same pinout; the TL072 has lower noise (low-noise version), the TL082 is the general-purpose version.
Pinout data comes from TI TL072 datasheet (standard DIP-8 numbering). Refer to the actual device datasheet as authoritative for the pinout.
