MCHPCAP1293-1-AC3-TR
Overview
The CAP1293-1-AC3-TR is a 3-channel capacitive touch sensor featuring integrated proximity detection and signal guarding. It operates over a wide 3V to 5.5V supply range and includes advanced filtering to mitigate environmental noise and RF interference in consumer and industrial designs.
Why Choose This Part
This sensor offers robust ESD protection of 8kV (HBM) and active signal guarding to reduce parasitic capacitance effects. Its low power profile, drawing only 5uA in deep sleep and 50uA in standby, makes it ideal for battery-operated devices requiring high responsiveness.
Applications
Key Specifications
Getting Started
Evaluation can be performed using Microchip hardware development tools or by interfacing the 8-TDFN package directly with a microcontroller via the SMBus/I2C interface. Firmware development is simplified by the device's automatic recalibration and programmable sensitivity registers which allow tuning for various overlay materials and thicknesses.
