Circuit Description
linear. For VR_BIAS values greater than 500KΩ, the mini-
mum detect level is typically determined more by the internal
device offsets, and thermal effects.
VOLTAGE COMPARATORS
The circuit includes four general purpose voltage compara-
tors that use an internal reference voltage to set their voltage
thresholds. Three of the comparators have their non-
inverting inputs tied to the internal reference voltage, and

their inverting-inputs are brought out. The remaining one
comparator has its inverting input tied to the internal voltage
reference, and its non-inverting input is brought out. All four
comparators include hysteresis to improve noise immunity.
The comparator outputs are internally pulled up to V
un-used comparator should have its input connected to de-
vice ground.
