# HT358ARTZ

**HTCSEMI** · Operational Amplifier · SOT23-8

HT358ARTZ from HTCSEMI, in a SOT23-8. 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 | OUTA | output | Output of amplifier A; the device can source or sink up to 100 mA maximum output current per the absolute maximum ratings. |
| 2 | -INA | input | Inverting input of amplifier A; input current is limited to 50 mA at VIN = -0.3 V and input voltage range is -0.3 V to +45 V. |
| 3 | +INA | input | Non-inverting input of amplifier A; common-mode input range includes ground (0 to VCC-1.5 V at 25 C). |
| 4 | -VS | power_in | Negative power supply (ground in single-supply operation); the device also operates from split supplies. |
| 5 | +INB | input | Non-inverting input of amplifier B; common-mode input range includes ground (0 to VCC-1.5 V at 25 C). |
| 6 | -INB | input | Inverting input of amplifier B; input current is limited to 50 mA at VIN = -0.3 V and input voltage range is -0.3 V to +45 V. |
| 7 | OUTB | output | Output of amplifier B; the device can source or sink up to 100 mA maximum output current per the absolute maximum ratings. |
| 8 | +VS | power_in | Positive power supply; maximum supply voltage is 45 V (testing performed at 36 V MAX VCC). |
