OPA349SA

Texas Instruments · Operational Amplifier · SC-70-5

OPA349SA from Texas Instruments, in a SC-70-5. 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 +In input Noninverting input with a common-mode range extending 200mV beyond the supply rails and a maximum input bias current of 10pA.
2 V- power_in Negative supply or ground, with total supply V+ to V- specified from 1.8V to 5.5V and bypassed with a 0.01µF ceramic capacitor.
3 -In input Inverting input with a common-mode range extending 200mV beyond the supply rails, diode-clamped to the rails and limited to 10mA if driven more than 0.5V beyond them.
4 Out output Rail-to-rail output that swings to within 350mV of the rails at 10kΩ load, with ±8mA output current and ±10mA short-circuit current.
5 V+ power_in Positive supply, specified from 1.8V to 5.5V (absolute maximum 5.5V between V+ and V-) and bypassed with a 0.01µF ceramic capacitor.
