HT8722BRZ

HTCSEMI · Operational Amplifier · SOP-8

HT8722BRZ 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 Channel A output; the datasheet states rail-to-rail output swing and an output current of ±30 mA at VS = 3 V and ±50 mA at VS = 5 V.
2 -IN A input Channel A inverting input; input voltage must stay between GND and VS per the absolute maximum ratings (table 3, page 4).
3 +IN A input Channel A non-inverting input; input voltage range is 0 V to 3 V at VS = 3 V and 0 V to 5 V at VS = 5 V (tables 1-2).
4 V- power_in Negative supply rail; the part operates from a single 2.7 V to 5.5 V supply with absolute maximum supply voltage of 6 V.
5 +IN B input Channel B non-inverting input; input voltage must stay between GND and VS per the absolute maximum ratings (table 3, page 4).
6 -IN B input Channel B inverting input; input voltage must stay between GND and VS per the absolute maximum ratings (table 3, page 4).
7 OUT B output Channel B output; the datasheet states rail-to-rail output swing and an output current of ±30 mA at VS = 3 V and ±50 mA at VS = 5 V.
8 V+ power_in Positive supply rail; the part operates from a single 2.7 V to 5.5 V supply with absolute maximum supply voltage of 6 V.
