CIRCUIT DESCRIPTION
Figure 3 shows the part operating near the minimum input
thresholds. As the sin wave input threshold is increased, the
low side clamps become active (Figure 4). Increasing the
amplitude further (Figure 5), the highside clamp becomes
active. These internal clamps allow for voltages up to 250 V
and 250 V on the sensor side of the setup (with R1 = R2 =
22 k) (reference the diagram page 1).
Figure 6 shows the effect using the diagnostic (DIAG)
function has on the circuit. The input threshold (negative) is
switched from a threshold of 160 mV to +160 mV when
DIAG goes from a low to a high. There is no hysteresis when
DIAG is high.
