detection and generation. These circuits consist of an
output buffer/drivers.
put sink when the voltage applied to the 鈥楾HRESHOLD鈥?/div>
terminal is less than 1.15V (the internal reference). The
ICL8212 requires a voltage in excess of 1.15V to switch its
output on (no current limit). Both devices have a low current
output (HYSTERESIS) which is switched on for input
voltages in excess of 1.15V. The HYSTERESIS output may
be used to provide positive and noise free output switching
using a simple feedback network.
