HT2282ARZ from HTCSEMI, in a SOP-8. 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 A | output | Output of amplifier A, which swings rail-to-rail, typically 300 mV from the rails into a 10 kΩ load (450 mV over -40 to 125 °C). |
| 2 | -In A | input | Inverting input of amplifier A; the input common-mode range extends to V- and the input must not exceed the supply by more than 300 mV without limiting input current to under 10 mA. |
| 3 | +In A | input | Non-inverting input of amplifier A; the input common-mode range extends to V- and the input must not exceed the supply by more than 300 mV without limiting input current to under 10 mA. |
| 4 | -Vs | power_in | Negative power supply (V-); total supply (+VS) - (-VS) is 3 V to 36 V, with an absolute maximum of 40 V. |
| 5 | +In B | input | Non-inverting input of amplifier B; the input common-mode range extends to V- and the input must not exceed the supply by more than 300 mV without limiting input current to under 10 mA. |
| 6 | -In B | input | Inverting input of amplifier B; the input common-mode range extends to V- and the input must not exceed the supply by more than 300 mV without limiting input current to under 10 mA. |
| 7 | Out B | output | Output of amplifier B, which swings rail-to-rail, typically 300 mV from the rails into a 10 kΩ load (450 mV over -40 to 125 °C). |
| 8 | +Vs | power_in | Positive power supply (V+); total supply (+VS) - (-VS) is 3 V to 36 V, with an absolute maximum of 40 V. |
