the amplifier offset, the output is left OPEN when the out-
put signal switches from positive to negative. The output
waveform is determined by the external circuit because
the IC impedance increases during this transition period.
Since inductive loads are usually provided, a capacitor
should be connected to suppress backlash voltages.
Output waveforms are shown in Fig. 9. Because of

Hall input signals of 50mV (peak to peak) or greater
should be applied between pins 9 and 10 and between
pins 11 and 12. The DC input range is 2V to
(Vreg
1.5V). There will be no problem if the input is cen-
tered around Vreg / 2.
Because the Hall input impedance is 1M
or grater, any
type of Hall device can be connected. No current flows
when the transistor is off because pins 9 and 10 as well
as pins 11 and 12 are differential inputs.
Because the IC is a linear driver, any DC offset in the Hall
device will be amplified and appear in the output. Use
Hall devices having a minimum offset. Hall devices can
be connected in either series or parallel.
