OPA4333M

HGSEMI · Operational Amplifier · SOP-14L

OPA4333M from HGSEMI, in a SOP-14L. 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 A output Channel A output; swings to within about 30 to 70 mV of the supply rails over temperature, with short-circuit current of about ±5 mA.
2 -IN A input Channel A inverting input; the common-mode range extends 0.1 V beyond each supply rail, and input current must be limited to 10 mA max if the input swings more than 0.3 V beyond a rail.
3 +IN A input Channel A non-inverting input; the common-mode range extends 0.1 V beyond each supply rail, and input current must be limited to 10 mA max if the input swings more than 0.3 V beyond a rail.
4 V+ power_in Positive power supply (highest potential); operating supply is 1.8 V to 5.5 V and must not exceed 7 V absolute maximum.
5 +IN B input Channel B non-inverting input; the common-mode range extends 0.1 V beyond each supply rail, and input current must be limited to 10 mA max if the input swings more than 0.3 V beyond a rail.
6 -IN B input Channel B inverting input; the common-mode range extends 0.1 V beyond each supply rail, and input current must be limited to 10 mA max if the input swings more than 0.3 V beyond a rail.
7 OUT B output Channel B output; swings to within about 30 to 70 mV of the supply rails over temperature, with short-circuit current of about ±5 mA.
8 OUT C output Channel C output; swings to within about 30 to 70 mV of the supply rails over temperature, with short-circuit current of about ±5 mA.
9 -IN C input Channel C inverting input; the common-mode range extends 0.1 V beyond each supply rail, and input current must be limited to 10 mA max if the input swings more than 0.3 V beyond a rail.
10 +IN C input Channel C non-inverting input; the common-mode range extends 0.1 V beyond each supply rail, and input current must be limited to 10 mA max if the input swings more than 0.3 V beyond a rail.
11 V- power_in Negative power supply (lowest potential); connect to ground for single-supply operation or to the negative rail for dual-supply operation.
12 +IN D input Channel D non-inverting input; the common-mode range extends 0.1 V beyond each supply rail, and input current must be limited to 10 mA max if the input swings more than 0.3 V beyond a rail.
13 -IN D input Channel D inverting input; the common-mode range extends 0.1 V beyond each supply rail, and input current must be limited to 10 mA max if the input swings more than 0.3 V beyond a rail.
14 OUT D output Channel D output; swings to within about 30 to 70 mV of the supply rails over temperature, with short-circuit current of about ±5 mA.
