EG Micro · Comparators · SOP-8

EG393 from EG Micro, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTA output Open-collector output of comparator A. Requires an external pull-up resistor to a supply rail (typ. 3k-100k). Can sink up to 16mA; absolute-max output-to-ground short-circuit current 20mA.
2 -INA input Inverting input of comparator A. Input common-mode range 0V to Vcc−1.5V; input bias current typ. 25nA, offset current typ. ±5nA.
3 +INA input Non-inverting input of comparator A. Input common-mode range extends down to ground and up to Vcc−1.5V.
4 GND power_in Ground / negative supply reference (V-). Tied to 0V in single-supply operation, or to the negative rail (down to −18V) in dual-supply operation.
5 +INB input Non-inverting input of comparator B. Input common-mode range extends down to ground and up to Vcc−1.5V.
6 -INB input Inverting input of comparator B. Input bias current typ. 25nA; input offset voltage typ. 1.0mV.
7 OUTB output Open-collector output of comparator B. Requires an external pull-up resistor to a supply rail. Can be wired-OR'd with OUTA on a shared pull-up. Sink current up to 16mA.
8 VCC power_in Positive supply. Single-supply range 2.0V to 36V, or +1V to +18V in split-supply operation. Typical quiescent current 0.8mA (independent of Vcc). No bypass capacitor is required for the bias network but standard decoupling is recommended.
