**HTCSEMI** · Operational Amplifier · SOP-8

HT2374BRZ 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 | OUTA | output | Amplifier A output; the voltage range extends to within millivolts of each supply rail. |
| 2 | INPA | input | Non-inverting input of amplifier A; voltage range can go from 0 to VDD. |
| 3 | INNA | input | Inverting input of amplifier A; has the same voltage range as INPA (0 to VDD). |
| 4 | GND | power_in | Ground pin; connect to the most negative supply. All GND pads are connected on die. |
| 5 | INPB | input | Non-inverting input of amplifier B; voltage range can go from 0 to VDD. |
| 6 | INNB | input | Inverting input of amplifier B; has the same voltage range as INPB (0 to VDD). |
| 7 | OUTB | output | Amplifier B output; the voltage range extends to within millivolts of each supply rail. |
| 8 | VDD | power_in | Positive power supply pin, 5V nominal; the device operates from 2.5 V to 5.5 V per the recommended operating conditions. |
