# AMC22C11DR

**Texas Instruments** · Isolated Comparators · SOIC-8

AMC22C11DR from Texas Instruments, 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 | VDD1 | power_in | High-side power supply, which should be decoupled as described in the Power Supply Recommendations section. |
| 2 | IN | input | Analog input pin to the comparator. |
| 3 | REF | passive | Reference pin that defines the trip threshold and affects hysteresis; it is tied to an internal 100μA current source, takes a resistor and a filter capacitor to GND1, and can also be driven by an external voltage source. |
| 4 | GND1 | power_in | High-side ground. |
| 5 | GND2 | power_in | Low-side ground. |
| 6 | OUT | output | Open-drain comparator output that must be connected to an external pullup resistor. |
| 7 | LATCH | input | Digital input that selects latch mode (high) or transparent mode (low) of the open-drain output; it must not be left floating and should be connected to GND2 when not used. |
| 8 | VDD2 | power_in | Low-side power supply, which should be decoupled as described in the Power Supply Recommendations section. |
