MC3303PWR

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).
