Overview

The CAP1208-1-A4-TR is an 8-channel capacitive touch sensor controller that provides a turnkey solution for adding touch-sensitive buttons and interfaces to embedded systems. It features multiple low-power modes, including a 5 uA deep sleep state, and utilizes integrated analog filtering and digital EMI blockers to maintain performance in noisy environments.

Why Choose This Part

This controller simplifies design by providing automatic recalibration and individual threshold programming for each of the eight buttons. It offers high reliability with an 8kV ESD rating and specific RF detection filters to prevent false triggers from mobile devices and wireless interference.

Applications

Home Automation Control Panels
Ideal for wall-mounted touch switches and lighting controllers requiring sleek, mechanical-free interfaces.
White Goods and Appliances
Provides durable, moisture-resistant touch controls for kitchen and laundry appliances.
Handheld Battery Devices
Low power consumption and standby modes make it suitable for battery-operated consumer electronics.
Volume and Slider Control
The press-and-hold feature facilitates volume ramp-up or menu scrolling in audio and navigation systems.

Getting Started

Engineers can interface with the CAP1208 using SMBus or I2C protocols, making it compatible with most microcontrollers. To evaluate the sensor, the CAP1208 Evaluation Board provides a reference circuit for testing electrode sensitivity and fine-tuning recalibration settings.
