MAX9018AEKA+T

Analog Devices Inc./Maxim Integrated · Comparators · SOT-23-8

MAX9018AEKA+T from Analog Devices Inc./Maxim Integrated, in a SOT-23-8. 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 OUTA output Comparator A open-drain output that requires an external pullup resistor and can be pulled up to 5.5V above VEE, beyond VCC.
2 REF/INA- output 1.24V reference output that is internally connected to the inverting input of comparator A, and can source and sink up to 100nA to external circuitry.
3 INA+ input Comparator A noninverting input with a common-mode range from VEE - 0.2V to VCC + 0.2V.
4 VEE power_in Negative supply voltage, normally ground.
5 INB+ input Comparator B noninverting input with a common-mode range from VEE - 0.2V to VCC + 0.2V.
6 INB- input Comparator B inverting input with a common-mode range from VEE - 0.2V to VCC + 0.2V.
7 OUTB output Comparator B open-drain output that requires an external pullup resistor and can be pulled up to 5.5V above VEE, beyond VCC.
8 VCC power_in Positive supply voltage, 1.8V to 5.5V operating range, with absolute maximum of 6V between VCC and VEE.
