**Texas Instruments** · Operational Amplifier · TSSOP-14

OPA4342EA from Texas Instruments, 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 | Out D | output | Output of amplifier D, which is rail-to-rail and can drive 600Ω loads connected to any potential between V+ and ground. |
| 2 | -In D | input | Inverting input of amplifier D; the input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10mA. |
| 3 | +In D | input | Non-inverting input of amplifier D; the common-mode voltage range extends 300mV beyond the supply rails. |
| 4 | +V | power_in | Negative power supply (single-supply ground); the specified supply range is 2.7V to 5.5V across V+ to V-, with an absolute maximum of 7.5V. |
| 5 | +In C | input | Non-inverting input of amplifier C; the common-mode voltage range extends 300mV beyond the supply rails. |
| 6 | -In C | input | Inverting input of amplifier C; the input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10mA. |
| 7 | Out C | output | Output of amplifier C, which is rail-to-rail and can drive 600Ω loads connected to any potential between V+ and ground. |
| 8 | Out A | output | Output of amplifier A, which is rail-to-rail and can drive 600Ω loads connected to any potential between V+ and ground. |
| 9 | -In A | input | Inverting input of amplifier A; the input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10mA. |
| 10 | +In A | input | Non-inverting input of amplifier A; the common-mode voltage range extends 300mV beyond the supply rails. |
| 11 | +V | power_in | Positive power supply; the specified supply range is 2.7V to 5.5V across V+ to V-, with an absolute maximum of 7.5V. |
| 12 | +In B | input | Non-inverting input of amplifier B; the common-mode voltage range extends 300mV beyond the supply rails. |
| 13 | -In B | input | Inverting input of amplifier B; the input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10mA. |
| 14 | Out B | output | Output of amplifier B, which is rail-to-rail and can drive 600Ω loads connected to any potential between V+ and ground. |
