OPA2344UA

Texas Instruments · Operational Amplifier · SOIC-8

OPA2344UA from Texas Instruments, in a SOIC-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, rail-to-rail output swinging within 1mV of the supplies.
2 -In A input Inverting input of amplifier A, diode-clamped to the supply rails with input current limited to 10mA.
3 +In A input Non-inverting input of amplifier A, common-mode range extends 300mV beyond the supplies.
4 V- power_in Negative supply (ground in single-supply use); total supply V+ to V- is 2.5V to 5.5V operating, 7.5V absolute maximum.
5 +In B input Non-inverting input of amplifier B, common-mode range extends 300mV beyond the supplies.
6 -In B input Inverting input of amplifier B, diode-clamped to the supply rails with input current limited to 10mA.
7 Out B output Output of amplifier B, rail-to-rail output swinging within 1mV of the supplies.
8 V+ power_in Positive supply, operating range 2.5V to 5.5V above V-, 7.5V absolute maximum.
