Nanopower Series anisotropic magnetoresistive (AMR) sensor IC, omnipolar, high sensitivity (14 G typ.), SOT-23, 3000 units/tape and 178 mm [7 in] reel Honeywell’s Nanopower Series anisotropic magnetoresistive (AMR) sensor ICs are ultra-sensitive devices designed to accommodate a wide range of applications with large air gaps, small magnetic fields and low power requirements. The sensor ICs respond to either a North or South pole applied in a direction parallel to the sensor. They do not require the magnet polarity to be identified, simplifying installation and potentially reducing system cost. These sensor ICs use a very low average current consumption and a push-pull output which does not require a pull-up resistor. The sensor ICs can operate from a supply voltage as low as 1.65 V, promoting energy efficiency. SM353LT: For applications requiring ultra high magnetic sensitivity (14 Gauss typical operate, 20 Gauss maximum operate) and a very low current draw (310 nA typical).
