THEORY OF OPERATION

NORMAL OPERATION

Figure 2 shows one channel of the CS1124 along with the

necessary external components. Both channels share the

INAdj pin as the negative input to a comparator. A brief

description of the components is as follows:

VRS – Ideal sinusoidal, ground referenced, sensor output

– amplitude usually increases with frequency, depending on

loading.

RRS – Source impedance of sensor.

R1/RAdj – External resistors for current limiting and

biasing.

INP1/INAdj – Internal current sources that determine trip

points via R1/RAdj.

COMP1 – Internal comparator with built–in hysteresis

set at 160 mV.

OUT1 – Output 0 V – 5.0 V square wave with the same

frequency as VRS.

By inspection, the voltage at the (+) and (–) terminals of

COMP1 with VRS = 0V are:

V+

+ INP1(R1 ) RRS)
