Product Description
Product Overview
The A3213 and A3214 are ultra-sensitive, pole-independent Hall-effect switches with a latched digital output. Designed for low-power applications, especially in battery-operated handheld equipment like cell phones and palmtop computers, these devices offer a wide operating voltage range (2.4 to 5.5 V) and reduced power consumption through a unique clocking scheme. They feature chopper stabilization for improved stability and are insensitive to physical stress, making them ideal replacements for reed switches with enhanced reliability and simplified manufacturing.
