All output-voltage measurements are made with a voltmeter having an input impedance of at least 10 kΩ.
Magnetic flux density is measured at most sensitive area of device located 0.0165" (0.42 mm) below the branded face of the ‘U’
package; 0.0195" (0.50 mm) below the branded face of the ‘UA’ package; and 0.0305" (0.775 mm) below the branded face of the
‘LT’ package.
