# AMC22C11QDRQ1

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

AMC22C11QDRQ1 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 with operating range 3 V to 25 V. |
| 2 | IN | input | Analog input pin to the comparator. |
| 3 | REF | input | Reference pin that defines the trip threshold with internal 100-μA current source; connect resistor from REF to GND1 to define threshold and capacitor to GND1 for filtering. |
| 4 | GND1 | power_in | High-side ground. |
| 5 | GND2 | power_in | Low-side ground. |
| 6 | OUT | output | Open-drain output of the comparator; connect to external pullup resistor. |
| 7 | LATCH | input | Digital input to select latch mode (high) or transparent mode (low); do not leave floating; connect to GND2 when not used. |
| 8 | VDD2 | power_in | Low-side power supply with operating range 2.7 V to 5.5 V. |
