HT277ARZ from HTCSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Output of op-amp A. Rail-to-rail output swing under light load; typical source current 1.5mA, sink current 3µA. Short-circuit protected to GND. |
| 2 | -IN1 | input | Inverting input of op-amp A. Very high input impedance; typical input bias current 1pA, input offset current 1pA, input offset voltage 1.5mV typ / 5mV max at VCC=3V. |
| 3 | +IN1 | input | Non-inverting input of op-amp A. Input common-mode range extends from V- (0V) to VCC-1.3V. |
| 4 | V- | power_in | Negative supply / ground rail. In single-supply operation this is tied to GND. Input common-mode range includes this rail. |
| 5 | +IN2 | input | Non-inverting input of op-amp B. Input common-mode range extends from V- (0V) to VCC-1.3V. |
| 6 | -IN2 | input | Inverting input of op-amp B. High input impedance; ~1pA input bias current. |
| 7 | OUT2 | output | Output of op-amp B. Rail-to-rail output swing under light load; short-circuit protected to GND. |
| 8 | VCC | power_in | Positive supply rail. Operating range 1.4V to 7V; absolute maximum 8.5V. Internally decouple with a ceramic capacitor to V-. |
