XD2903

XINLUDA · Comparators · DIP-8

XD2903 from XINLUDA, in a DIP-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 1OUT output Output of comparator 1, an open-drain NPN that sinks current when IN+ is higher than IN- plus the offset voltage, so it needs an external pull-up.
2 1IN- input Negative (inverting) input of comparator 1; its upper common-mode limit is Vcc - 1.5 V at 25°C.
3 1IN+ input Positive (non-inverting) input of comparator 1; it can exceed the Vcc level and either input can go to 30 V without damage on non-V devices.
4 GND power_in Ground pin; the input and common-mode voltages must not go below 0.3 V under ground (network ground).
5 2IN+ input Positive (non-inverting) input of comparator 2; it can exceed the Vcc level and either input can go to 30 V without damage on non-V devices.
6 2IN- input Negative (inverting) input of comparator 2; its upper common-mode limit is Vcc - 1.5 V at 25°C.
7 2OUT output Output of comparator 2, an open-drain NPN that sinks current when IN+ is higher than IN- plus the offset voltage, so it needs an external pull-up.
8 VCC power_in Supply pin; the recommended supply range for non-V devices such as the XD2903 is 2 V to 30 V.
