描述

The AS7150 is a compact, ultra-low power analog frontend (AFE) designed for optical force and touch sensing. It enables force and touch detection on virtually any surface—including wet, gloved, or thick/stiff materials—making it ideal for next-generation human-machine interfaces.
With high displacement resolution (<1µm), ultra-low noise, and flexible connectivity to a variety of optical frontends (OFEs), the AS7150 is the core of discrete force sensing solutions for applications where size and power efficiency are critical. This product is part of our Optical Force family.

特点

  • 2 ADCs for simultaneous photodiode acquisition
  • 3 photodiode and 3 LED inputs
  • Integrated proximity detection
  • On-chip oscillator
  • I2C digital interface for easy system integration
  • Supports ultra-slim and compact form factors

优势

  • Intuitive, Multimodal Interaction: Supports “force touch” and multi-modal buttons, allowing a single interface to detect different pressure levels (soft, medium, hard) for more intuitive and space-saving controls
  • Works Under Any Surface: Reliable detection even with wet fingers, gloves, or styluses, and can be used behind thick or stiff surfaces without compromising water resistance
  • Ultra-Low Power & Small Size: Perfect for battery-powered and space-constrained devices
  • Flexible Integration
  • High Sensitivity
  • Robust & Reliable
