HT8515ARTZ from HTCSEMI, 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, which swings rail-to-rail and is rated for a 20 mA short-circuit limit (ISC) with duration to GND per the derating curves. |
| 2 | -Vs | power_in | Negative supply rail; the total supply voltage must not exceed the 6 V absolute maximum rating. |
| 3 | +In | input | Non-inverting input with a 0 V to VS input voltage range, where input current must be limited to 5 mA or less by external series resistance. |
| 4 | -In | input | Inverting input with the same 0 V to VS input voltage range, where input current must be limited to 5 mA or less by external series resistance. |
| 5 | +Vs | power_in | Positive supply rail; the part operates from a 1.8 V to 5 V single supply, with a 6 V absolute maximum. |
