LMX324IPT from STMicroelectronics, in a TSSOP-14. 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 | Out1 | output | Amplifier 1 output with rail-to-rail swing, within 180 mV max of the rails into a 10 kΩ load to VCC/2. |
| 2 | In1- | input | Amplifier 1 inverting input, limited to Vcc- - 0.3 V to Vcc+ + 0.3 V and requiring a series resistor limiting input current to 10 mA. |
| 3 | In1+ | input | Amplifier 1 non-inverting input with common-mode range of Vcc- - 0.2 V to Vcc+ - 1 V, which includes ground. |
| 4 | Vcc+ | power_in | Positive supply for all four amplifiers, operating range 2.3 V to 5.5 V (absolute max 6 V), with 10 nF decoupling placed close to the pin. |
| 5 | In2+ | input | Amplifier 2 non-inverting input with common-mode range of Vcc- - 0.2 V to Vcc+ - 1 V, which includes ground. |
| 6 | In2- | input | Amplifier 2 inverting input, limited to Vcc- - 0.3 V to Vcc+ + 0.3 V and requiring a series resistor limiting input current to 10 mA. |
| 7 | Out2 | output | Amplifier 2 output with rail-to-rail swing, within 180 mV max of the rails into a 10 kΩ load to VCC/2. |
| 8 | Out3 | output | Amplifier 3 output with rail-to-rail swing, within 180 mV max of the rails into a 10 kΩ load to VCC/2. |
| 9 | In3- | input | Amplifier 3 inverting input, limited to Vcc- - 0.3 V to Vcc+ + 0.3 V and requiring a series resistor limiting input current to 10 mA. |
| 10 | In3+ | input | Amplifier 3 non-inverting input with common-mode range of Vcc- - 0.2 V to Vcc+ - 1 V, which includes ground. |
| 11 | Vcc- | power_in | Negative supply (ground in single-supply use) for all four amplifiers, with 10 nF decoupling placed close to the pin. |
| 12 | In4+ | input | Amplifier 4 non-inverting input with common-mode range of Vcc- - 0.2 V to Vcc+ - 1 V, which includes ground. |
| 13 | In4- | input | Amplifier 4 inverting input, limited to Vcc- - 0.3 V to Vcc+ + 0.3 V and requiring a series resistor limiting input current to 10 mA. |
| 14 | Out4 | output | Amplifier 4 output with rail-to-rail swing, within 180 mV max of the rails into a 10 kΩ load to VCC/2. |
