HAD8541ARTZ

HXY MOSFET · Operational Amplifier · SOT-23-5L

HAD8541ARTZ from HXY MOSFET, in a SOT-23-5L. 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 output Amplifier output with rail-to-rail swing, within 10 mV of the supply rail at light loads (>100 kΩ) and about 60 mV at 10 kΩ, and it needs an isolation resistor for large capacitive loads.
2 -VS power_in Negative supply (ground in single-supply operation), bypassed with a 0.1 µF ceramic capacitor, with total supply +VS to -VS of 2.2 V to 5.5 V and 7 V absolute maximum.
3 +IN input Non-inverting input with rail-to-rail common-mode range from (-VS) - 0.1 V to (+VS) + 0.1 V.
4 -IN input Inverting input with rail-to-rail common-mode range from (-VS) - 0.1 V to (+VS) + 0.1 V.
5 +VS power_in Positive supply, operating range 2.2 V to 5.5 V (7 V absolute maximum between +VS and -VS), bypassed with a 0.1 µF ceramic capacitor placed close to the pin.
