Analog Devices Inc Maxim Integrated · Operational Amplifier · SOIC-8

MAX44246ASA+ from Analog Devices Inc Maxim Integrated, in a SOIC-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 Channel A output, which is rail-to-rail; the output short-circuit duration to either supply rail is limited to 1s, and noncontinuous sink/source current is 40mA/30mA.
2 INA- input Channel A negative (inverting) input; the input common-mode range is (VGND - 0.05V) to (VDD - 1.5V), and differential input voltage is limited to ±6V with differential input current limited to ±20mA.
3 INA+ input Channel A positive (non-inverting) input; the input common-mode range is (VGND - 0.05V) to (VDD - 1.5V), and the input is protected by internal back-to-back clamp diodes with no current-limiting resistors.
4 VSS power_in Negative supply voltage, which is 0V (GND) in single-supply operation or −1.35V to −18V in dual-supply operation.
5 INB+ input Channel B positive (non-inverting) input; the input common-mode range is (VGND - 0.05V) to (VDD - 1.5V), and the input is protected by internal back-to-back clamp diodes with no current-limiting resistors.
6 INB- input Channel B negative (inverting) input; the input common-mode range is (VGND - 0.05V) to (VDD - 1.5V), and differential input voltage is limited to ±6V with differential input current limited to ±20mA.
7 OUTB output Channel B output, which is rail-to-rail; the output short-circuit duration to either supply rail is limited to 1s, and noncontinuous sink/source current is 40mA/30mA.
8 VDD power_in Positive supply voltage, operating from 2.7V to 36V single supply or ±1.35V to ±18V dual supplies, with an absolute maximum supply voltage of 40V.
