CONNTEK · Operational Amplifier · SOT-23-5
KTA333-ST5 from CONNTEK, 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 that swings within 100 mV of the supply rails with a 10 kΩ load. |
| 2 | V- | power_in | Negative supply (lowest potential), used with 1.8 V to 5.5 V single supply or ±0.9 V to ±2.75 V dual supply. |
| 3 | IN+ | input | Non-inverting input whose common-mode range extends 100 mV beyond the supply rails, and input currents above 10 mA can cause permanent damage, so an input resistor is recommended. |
| 4 | IN- | input | Inverting input with the same common-mode range of 100 mV beyond the supply rails, and input currents above 10 mA can cause permanent damage. |
| 5 | V+ | power_in | Positive supply (highest potential), with absolute maximum supply voltage of 6.5 V and a 0.1 µF bypass capacitor recommended close to the pin. |
