HT8527ARZ 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 | Amplifier A rail-to-rail output, with output swing within 35 mV of each rail at 250 µA load. |
| 2 | -IN A | input | Amplifier A inverting input, rail-to-rail, with input fault current limited to 5 mA by external series resistance. |
| 3 | +IN A | input | Amplifier A non-inverting input, rail-to-rail, with input fault current limited to 5 mA by external series resistance. |
| 4 | V- | power_in | Negative supply or ground, with the datasheet characterized at V- = 0 V for single-supply operation. |
| 5 | +IN B | input | Amplifier B non-inverting input, rail-to-rail, with input fault current limited to 5 mA by external series resistance. |
| 6 | -IN B | input | Amplifier B inverting input, rail-to-rail, with input fault current limited to 5 mA by external series resistance. |
| 7 | OUT B | output | Amplifier B rail-to-rail output, with output swing within 35 mV of each rail at 250 µA load. |
| 8 | V+ | power_in | Positive supply, operating from 1.8 V to 6 V with 6 V absolute maximum supply voltage. |
