OPA2349EA

Texas Instruments · Operational Amplifier · SOT-23-8

OPA2349EA from Texas Instruments, in a SOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTA output Amplifier A output. Rail-to-rail output stage; swings to within 350mV of either supply rail with a 10kΩ load. Output current ±8mA typ; short-circuit current ±10mA.
2 -INA input Inverting input of amplifier A. Common-mode range (V-)-0.2V to (V+)+0.2V; input bias current ±0.5pA typ, ±10pA max; differential input impedance 10^13Ω
3 +INA input Non-inverting input of amplifier A. Common-mode range (V-)-0.2V to (V+)+0.2V; input bias current ±0.5pA typ, ±10pA max. Diode-clamped to the supply rails - limit input current to 10mA if signals exceed rails by more than 0.5V.
4 V- power_in Negative supply (or ground in single-supply operation). Total supply (V+)-(V-) range: 1.8V to 5.5V; absolute maximum 5.5V across the two supply pins. Quiescent current 1µA typ per amplifier.
5 +INB input Non-inverting input of amplifier B. Common-mode range (V-)-0.2V to (V+)+0.2V; input bias current ±0.5pA typ, ±10pA max. Diode-clamped to the supply rails.
6 -INB input Inverting input of amplifier B. Common-mode range (V-)-0.2V to (V+)+0.2V; input bias current ±0.5pA typ, ±10pA max; differential input impedance 10^13Ω
7 OUTB output Amplifier B output. Rail-to-rail output stage; swings to within 350mV of either supply rail with a 10kΩ load. Output current ±8mA typ; short-circuit current ±10mA.
8 V+ power_in Positive supply. Specified range 1.8V to 5.5V referenced to V-; bypass with a 0.01µF ceramic capacitor close to the pin. Absolute maximum V+ to V-: 5.5V.
