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

MC3303PWR 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 | 1OUT | output | Output of amplifier 1, which swings from the negative supply to VCC+ - 1.5 V and is short-circuit protected (IOS typically ±30 mA at 25°C). |
| 2 | 1IN- | input | Inverting input of amplifier 1; neither input may be driven more positive than VCC+ or more negative than VCC- (input voltage limit ±18 V). |
| 3 | 1IN+ | input | Non-inverting input of amplifier 1; the common-mode input range includes the negative supply and extends to 2 V below VCC+. |
| 4 | VCC+ | power_in | Positive supply: 3 V to 36 V single-supply or split supplies with a total difference of 3 V to 36 V (recommended 5 V to 30 V; VCC+ with respect to VCC- maximum 36 V). |
| 5 | 2IN+ | input | Non-inverting input of amplifier 2; the common-mode input range includes the negative supply and extends to 2 V below VCC+. |
| 6 | 2IN- | input | Inverting input of amplifier 2; neither input may be driven more positive than VCC+ or more negative than VCC- (input voltage limit ±18 V). |
| 7 | 2OUT | output | Output of amplifier 2, which swings from the negative supply to VCC+ - 1.5 V and is short-circuit protected (IOS typically ±30 mA at 25°C). |
| 8 | 3OUT | output | Output of amplifier 3, which swings from the negative supply to VCC+ - 1.5 V and is short-circuit protected (IOS typically ±30 mA at 25°C). |
| 9 | 3IN- | input | Inverting input of amplifier 3; neither input may be driven more positive than VCC+ or more negative than VCC- (input voltage limit ±18 V). |
| 10 | 3IN+ | input | Non-inverting input of amplifier 3; the common-mode input range includes the negative supply and extends to 2 V below VCC+. |
| 11 | VCC- | power_in | Negative supply (ground in single-supply operation); for split supplies the recommended range is -2.5 V to -15 V. |
| 12 | 4IN+ | input | Non-inverting input of amplifier 4; the common-mode input range includes the negative supply and extends to 2 V below VCC+. |
| 13 | 4IN- | input | Inverting input of amplifier 4; neither input may be driven more positive than VCC+ or more negative than VCC- (input voltage limit ±18 V). |
| 14 | 4OUT | output | Output of amplifier 4, which swings from the negative supply to VCC+ - 1.5 V and is short-circuit protected (IOS typically ±30 mA at 25°C). |
