LM833M

HGSEMI · Low Noise Amplifiers (LNA) - RF · SOP-8

LM833M from HGSEMI, in a SOP-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 OUT1 output Amplifier 1 output. Push-pull output stage with no deadband crossover distortion, symmetrical source/sink AC response, capable of driving 2 kΩ loads to within ~1.3 V of the supply rails.
2 IN1- input Amplifier 1 inverting input. High-impedance bipolar input, typical input bias current 300 nA, input offset voltage 0.3 mV typ. Common-mode range typically −12 V to +14 V on ±15 V supplies.
3 IN1+ input Amplifier 1 non-inverting input. High-impedance bipolar input, typical input bias current 300 nA. Input voltage must not exceed VCC/VEE magnitude; absolute maximum input voltage ±15 V.
4 VCC- power_in Negative supply rail (VEE). Typical operation at −15 V; total supply (VCC to VEE) rated 36 V max. Quiescent current 4 mA typ for both amplifiers.
5 IN2+ input Amplifier 2 non-inverting input. High-impedance bipolar input, typical input bias current 300 nA. Input voltage must not exceed VCC/VEE magnitude; absolute maximum input voltage ±15 V.
6 IN2- input Amplifier 2 inverting input. High-impedance bipolar input, typical input bias current 300 nA, input offset voltage 0.3 mV typ.
7 OUT2 output Amplifier 2 output. Push-pull output stage with no deadband crossover distortion, symmetrical source/sink AC response, capable of driving 2 kΩ loads to within ~1.3 V of the supply rails.
8 VCC+ power_in Positive supply rail (VCC). Typical operation at +15 V; total supply (VCC to VEE) rated 36 V max. Bypass with a local ceramic capacitor to the negative rail.
