MAX4505EUK+T

Maxim Integrated · Interface - Specialized · SOT-23-5

MAX4505EUK+T from Maxim Integrated, in a SOT-23-5. 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 AIN input Analog fault-protected input, which withstands overvoltage up to ±36V with power on and ±40V with power off.
2 V+ power_in Positive supply voltage input; the datasheet specifies +9V to +36V for single-supply operation and ±8V to ±18V for dual supplies.
3 AOUT output Analog signal output, which is not fault protected; signals exceeding V+ or V- are clamped by internal diodes, so forward diode current must be limited to the maximum current rating.
4 N.C. unconnected No connection; the pin is not internally connected.
5 V- power_in Negative supply voltage input; the datasheet specifies -8V to -18V for dual-supply operation and 0V (ground) for single-supply operation.
