OPA244NA

Texas Instruments · Operational Amplifier · SOT-23-5

OPA244NA from Texas Instruments, in a SOT-23-5. 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 Out output Amplifier output; the datasheet specifies swing to within about 0.75 V of V+ and 0.1 V of ground for RL = 20kΩ to ground, with short-circuit current of -25/+12 mA.
2 V- power_in Negative supply rail; ground for single-supply operation, with the supply range given as 2.2 V to 36 V single supply or ±1.1 V to ±18 V dual supply.
3 +In input Non-inverting input; the common-mode voltage range is 0 V to (V+) - 0.9 V and includes ground, and inputs are diode-clamped to the rails with input current limited to 10 mA if the input can exceed a rail by more than 0.3 V.
4 -In input Inverting input; the common-mode voltage range is 0 V to (V+) - 0.9 V and inputs are diode-clamped to the rails with input current limited to 10 mA if the input can exceed a rail by more than 0.3 V.
5 V+ power_in Positive supply rail; specified from +2.6 V to +36 V single supply (minimum operating voltage +2.2 V), with absolute maximum supply voltage of 36 V.
