HT8542ARZ

HTCSEMI · Operational Amplifier · SOP-8

HT8542ARZ 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 Output of amplifier A, which has rail-to-rail output swing.
2 -IN A input Inverting input of amplifier A; input voltage must stay between GND and VS (absolute maximum ratings).
3 +IN A input Noninverting input of amplifier A; input voltage must stay between GND and VS (absolute maximum ratings).
4 V- power_in Negative supply pin; the part is specified for single-supply operation from 2.7 V to 5.5 V.
5 +IN B input Noninverting input of amplifier B; input voltage must stay between GND and VS (absolute maximum ratings).
6 -IN B input Inverting input of amplifier B; input voltage must stay between GND and VS (absolute maximum ratings).
7 OUT B output Output of amplifier B, which has rail-to-rail output swing.
8 V+ power_in Positive supply pin; the part is specified from 2.7 V to 5.5 V, with a 6 V absolute maximum supply voltage.
