OPA2343EA

Texas Instruments · Operational Amplifier · VSSOP-8

OPA2343EA from Texas Instruments, in a VSSOP-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 about 1 to 5 mV of the supply rails at a 100kΩ load, with short-circuit current continuous (one amplifier per package).
2 -In A input Inverting input of amplifier A; input signals that swing more than 0.5V beyond the supply rails should be current-limited to 10mA or less.
3 +In A input Non-inverting input of amplifier A, whose common-mode range extends from -0.3V to (V+) + 0.3V.
4 V- power_in Negative supply rail (ground in single-supply operation); total supply operating range is 2.5V to 5.5V.
5 +In B input Non-inverting input of amplifier B, whose common-mode range extends from -0.3V to (V+) + 0.3V.
6 -In B input Inverting input of amplifier B; input signals that swing more than 0.5V beyond the supply rails should be current-limited to 10mA or less.
7 Out B output Output of amplifier B, which swings to within about 1 to 5 mV of the supply rails at a 100kΩ load, with short-circuit current continuous (one amplifier per package).
8 V+ power_in Positive supply rail; specified from 2.7V to 5V (operating 2.5V to 5.5V), with power-supply pins bypassed by 0.01µF ceramic capacitors.
