OPA2337UA

Texas Instruments · Operational Amplifier · SOIC-8

OPA2337UA from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTA output Output of channel A. Rail-to-rail output swing; short-circuit protected (continuous, one amplifier per package).
2 -INA input Inverting input of channel A. FET input, IB = 10 pA max. Input voltage clamped to (V-) - 0.5 V to (V+) + 0.5 V by internal diodes; max input current 10 mA.
3 +INA input Non-inverting input of channel A. FET input, IB = 10 pA max. Common-mode range includes V- (ground in single-supply operation).
4 V- power_in Negative supply rail (or ground in single-supply operation). Total supply (V+) - (V-) rated 2.5 V to 5.5 V (7.5 V absolute maximum). Bypass with a 0.1 µF ceramic capacitor close to the pin.
5 +INB input Non-inverting input of channel B. FET input, IB = 10 pA max. Common-mode range includes V-.
6 -INB input Inverting input of channel B. FET input, IB = 10 pA max. Input voltage clamped to (V-) - 0.5 V to (V+) + 0.5 V by internal diodes; max input current 10 mA.
7 OUTB output Output of channel B. Rail-to-rail output swing; short-circuit protected (continuous, one amplifier per package).
8 V+ power_in Positive supply rail. Total supply (V+) - (V-) rated 2.5 V to 5.5 V (7.5 V absolute maximum). Bypass with a 0.1 µF ceramic capacitor close to the pin.
