AD-Series GMR Switches AD-Series GMR Switch™ Precision Digital Magnetic Sensors Functional Diagram Features • Digital outputs • Precision operate points from 1 – 8 mT (10 – 80 Oe) • 3 V – 6 V and 4.5 V – 30 V versions • 20 mA output drive • Temperature and voltage stability • Available with short-circuit protection • Standard or cross-axis orientation • Frequency response to 100 kHz • Ultraminiature TDFN6 and MSOP8 packages Vcc Short- Voltage Circuit Regulator Protection (optional) (optional) GMR Sensor Comparator Element Output Driver OUT Applications • Motion, speed, and position control • Pneumatic cylinder position sensing • Speed sensing GND Description AD-Series GMR Switches are the industry standard for sensitivity and precision. Idealized Transfer Function GMR Switches integrate GMR sensor elements with digital signal processing electronics. These sensors are more precise than other magnetic sensors, and magnetic field operate points are stable over voltage and temperature extremes. AD-Series models available in a wide variety of magnetic operate points and output configurations. Versions are available with short-circuit protection circuitry and with integrated voltage regulators. 1 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 sensor-info@nve.com www.nve.com ©NVE Corporation AD-Series GMR Switches Absolute Maximum Ratings Parameter Supply voltage Symbol AD08x AD8xx/AD9xx All others Output voltage Continuous output current Operating temperature Storage temperature ESD Applied magnetic field VCC Min. −0.5 −0.5 −33 −0.5 −40 −65 B Max. 7 33 33 33 24 125 150 2000 Unlimited Units Test Conditions Volts Volts mA °C °C Volts tesla Human Body Model 2 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 sensor-info@nve.com www.nve.com ©NVE Corporation AD-Series GMR Switches Operating Specifications Tmin to Tmax; 4.5 V < VCC < 30 V unless otherwise stated.
