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

HT4560BRZ 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 | A OUTPUT | output | Output of amplifier A; the datasheet rates the output current at ±50 mA maximum. |
| 2 | A -INPUT | input | Inverting input of amplifier A; the input voltage is limited to ±15 V (equal to the supply voltage for supplies below ±15 V). |
| 3 | A +INPUT | input | Non-inverting input of amplifier A; the input voltage is limited to ±15 V (equal to the supply voltage for supplies below ±15 V). |
| 4 | V- | power_in | Negative supply rail; the datasheet specifies an operating supply of ±2 V to ±18 V with an absolute maximum supply of ±18 V. |
| 5 | B +INPUT | input | Non-inverting input of amplifier B; the input voltage is limited to ±15 V (equal to the supply voltage for supplies below ±15 V). |
| 6 | B -INPUT | input | Inverting input of amplifier B; the input voltage is limited to ±15 V (equal to the supply voltage for supplies below ±15 V). |
| 7 | B OUTPUT | output | Output of amplifier B; the datasheet rates the output current at ±50 mA maximum. |
| 8 | V+ | power_in | Positive supply rail; the datasheet specifies an operating supply of ±2 V to ±18 V with an absolute maximum supply of ±18 V. |
