AH350 Datasheet | Anachip

Features - Extremely Sensitive - Flat Response to 23 KHz - Low-Noise Output - 4.5V to 6V Operation - SIP-3L and SOT23-3L Package - General Description The AH350 Hall-effect sensors accurately track extremely small changes in magnetic flux density- changes are generally too small to operate Hall-effect switches. As motion detectors, gear tooth sensors, and proximity detectors, they are magnetically driven mirrors of mechanical events. As sensitive monitors of electromagnets, they can effectively measure system’s performance with negligible system loading while providing isolation from contaminated and electrically noisy environments. Each Hall-effect integrated circuit includes a Hall sensing element, linear amplifier, and emitter-follower output stage. Having the Hall cell and amplifier on a single chip minimizes problems associated with handling tiny analog signals. The device is rated for continuous operation over the temperature range of -20°C to +85°C. - Application - Gear tooth Sensor - Notch Sensor - Current Sensor - Pin Assignment (Top View) 3. OUTPUT 2.
