OPA2349UA

Texas Instruments · Operational Amplifier · SOP-8

OPA2349UA from Texas Instruments, 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, which swings to within 350mV of the rails with a 10kΩ load and supplies up to ±8mA output current.
2 -In A input Inverting input of amplifier A, whose common-mode voltage range extends 200mV beyond the supply rails.
3 +In A input Non-inverting input of amplifier A, whose common-mode voltage range extends 200mV beyond the supply rails.
4 V- power_in Negative power supply, which serves as ground in single-supply operation; the total supply V+ to V- is specified from 1.8V to 5.5V.
5 +In B input Non-inverting input of amplifier B, whose common-mode voltage range extends 200mV beyond the supply rails.
6 -In B input Inverting input of amplifier B, whose common-mode voltage range extends 200mV beyond the supply rails.
7 Out B output Output of amplifier B, which swings to within 350mV of the rails with a 10kΩ load and supplies up to ±8mA output current.
8 V+ power_in Positive power supply, specified from 1.8V to 5.5V relative to V-, and should be bypassed with 0.01µF ceramic capacitors.
