QT1080-ISG

QT1080-ISG is a capacitive touch sensor IC (QT1080 family) used to implement touch buttons or sliders. It senses finger proximity via self-capacitance on multiple channels and reports touches to a microcontroller.
Key points
- Multi-channel: typically supports up to 8 touch channels (buttons/slots).
- Auto-calibration and filtering: robust against noise, with adjustable sensitivity and debounce.
- Low power: includes power-saving modes and wake-on-touch.
- Outputs/interface: digital outputs or a simple serial interface to a host MCU; supports guard/shield configurations for reliable panel sensing.
- Packaging/grade: “-ISG” often denotes a specific industrial/packaging variant; check the datasheet for exact package, voltage range, and temperature spec.
Common applications
- Capacitive push buttons, sliders, or proximity sensing in consumer electronics, appliances, remotes, and wearables.
Note
- For precise channel count, voltage range, timing, and interface details, consult the QT1080-ISG datasheet. If you meant a different part or variant, please provide context.

QT1080-ISG is in an 8-pin surface-mount SOIC (SOP-8) package.

- Pin count: 16 pins (likely in a 16‑pin package such as QFN/SOIC-16)
- Function: QT1080-ISG is a capacitive touch sensor IC; detects touch on a capacitive pad and reports the event to a host microcontroller via an I2C/serial interface (touch button input).
