OPA2348AID

UMW · Operational Amplifier · SOP-8

OPA2348AID 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 Channel A output; with RL = 100kΩ the output swings within 25 mV of the rail (AOL > 94 dB) at 25°C.
2 -In A input Channel A inverting input; the common-mode voltage range extends from (V-) - 0.2 V to (V+) + 0.2 V.
3 +In A input Channel A non-inverting input; rail-to-rail input with input bias current of ±0.5 pA typical.
4 V- power_in Negative supply rail; specified single-supply operation is 2.5 V to 5.5 V (minimum operating voltage 2.1 V).
5 +In B input Channel B non-inverting input; rail-to-rail input with input bias current of ±0.5 pA typical.
6 -In B input Channel B inverting input; the common-mode voltage range extends from (V-) - 0.2 V to (V+) + 0.2 V.
7 Out B output Channel B output; with RL = 100kΩ the output swings within 25 mV of the rail (AOL > 94 dB) at 25°C.
8 V+ power_in Positive supply rail; specified single-supply operation is 2.5 V to 5.5 V (minimum operating voltage 2.1 V).
