HT4040BRTZ from HTCSEMI, in a SOT-23-5. 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 | INP | input | Non-inverting analog input of the amplifier. Input common-mode voltage range is 0 V to VDD (beyond-the-rails capable). |
| 2 | GND | power_in | Ground / negative supply. Connect to the most negative supply rail; all GND pads are connected on die. |
| 3 | INN | input | Inverting analog input of the amplifier. Same input voltage range as INP (0 V to VDD, beyond-the-rails capable). |
| 4 | OUT | output | Amplifier output. Rail-to-rail output, swings to within ~10mV of each supply rail; short-circuit current ~80mA. |
| 5 | VDD | power_in | Positive power supply pin. Operating range 2.5 V to 5.5 V (absolute maximum 6 V). Bypass with a local decoupling capacitor to GND. |
