LMV612MAX

UMW · Operational Amplifier · SOP-8

LMV612MAX from UMW, in a SOP-8. 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 Output of amplifier A; input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V, and continuous output current above 45 mA adversely affects reliability.
2 -IN A input Inverting input of amplifier A; input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V, with a common-mode range extending about 200 mV beyond each supply rail at 25 °C.
3 +IN A input Non-inverting input of amplifier A; the input common-mode voltage range extends about 200 mV beyond each supply rail at 25 °C.
4 V- power_in Negative power supply; for single-supply operation this is connected to GND (0 V), and the total supply (V+ − V-) is 1.8 V to 5.5 V recommended with 6 V absolute maximum.
5 +IN B input Non-inverting input of amplifier B; the input common-mode voltage range extends about 200 mV beyond each supply rail at 25 °C.
6 -IN B input Inverting input of amplifier B; input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V, with a common-mode range extending about 200 mV beyond each supply rail at 25 °C.
7 OUT B output Output of amplifier B; input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V, and continuous output current above 45 mA adversely affects reliability.
8 V+ power_in Positive power supply; recommended supply voltage is 1.8 V to 5.5 V, with 6 V absolute maximum for V+ − V-.
