SS495A1-S
Overview
The SS495A1-S is a high-performance linear Hall effect sensor designed to provide a ratiometric analog output proportional to magnetic flux density. It features a quad-Hall integrated circuit design that minimizes mechanical stress effects while providing temperature-compensated magnetics for stability across a wide -40 to 150 degrees Celsius range. This surface-mount component is ideal for precision sensing in harsh environments where rail-to-rail operation and high sensitivity are required.
Why Choose This Part
The sensor offers a high sensitivity of 3.125 mV/Gauss and laser-trimmed thin film resistors that ensure high accuracy of 1.5 percent. Its rail-to-rail ratiometric output provides a wide dynamic range, while the quad-Hall element design significantly reduces sensitivity to mounting stress and thermal drift.
Applications
Key Specifications
Getting Started
To evaluate the SS495A1-S, connect the VDD pin to a stable 4.5V to 10.5V DC supply and the GND pin to system ground. The analog output can be interfaced directly to a microcontroller ADC, where the null voltage is typically half of VDD; use a decoupling capacitor near the sensor pins to minimize noise in high-current switching environments.
