A 0.8 x 0.4 inch (21 x 10 mm) breakout board with the ALT023-10E high sensitivity Tunneling Magnetoresistance (TMR) analog bridge magnetometer.
The board has a pre-soldered sensor and footprints for a standard 0.1" (2.54 mm) header and a common, 1 mm pitch card-edge connector.
The board can be powered by a 0 to 10 V power supply and provides a linear, differential output voltage.
The unique AHK991-14E is a high-field, low voltage, low power, TMR magnetic switch, designed for MRI detection in implantable medical devices.
The sensors have a 350 mT (3500 Oe) typical operate point, which is high enough to detect MRI fields or strong, rare-earth magnets in close proximity. Such high fields disrupt most other magnetic sensors.
The sensors can withstand unlimited fields without
being damaged or turning off.
Unlike Hall effect or other sensors, the switch is sensitive to magnetic fields in any direction.
Key Specifications:
350 mT operate point
0.9 to 1.8 V
2 µA typical supply current
3000 Hz switching speed
-40 to 85°C

GMR Switch Evaluation Kits.
This Evaluation Board is a complete isolated RS-485 node using the IL4685E isolated transceiver with integrated isolated DC-DC convertor.
These 2 x 3.5-inch (50 x 90 mm) boards include screw terminals and test pads. LEDs indicate DC-to-DC convertor input and output power. A 2s2p board with vias optimizes thermal performance.
The IL4685E is a high-speed, fully-isolated, half-duplex differential bus transceiver with an integrated DC-to-DC convertor to create an isolated 3.3 volt bus supply using the 3.3 volt controller supply. This level of integration dramatically reduces chip count and board area.
The IL612A-3E is a 3.3/5V, dual-channel, 10 Mbps isolated signal coupler with open-drain outputs, which can be used to replace opto-couplers in many standard isolation functions. The devices are manufactured with NVE's IsoLoop spintronic GMR technology giving exceptional small size and low power dissipation. The passive input structure allows direct interface to a very wide range of voltage inputs. A single resistor is used to set maximum current for input voltages above 0.5 V. 20 kV/microsecond transient immunity. 8-pin SOIC package.
This part is lead (Pb) free.
