CS209A  
Proximity Detector  
Description  
Features  
The CS209A is a bipolar monolithic  
integrated circuit for use in metal detec-  
tion/proximity sensing applications.  
feedback circuit provides drive to main-  
tain oscillation. The peak demodulator  
senses the negative portion of the oscil-  
Separate Current  
Regulator for Oscillator  
Negative Transient  
The IC (see block diagram) contains two lator envelop and provides a demodu-  
on-chip current regulators, oscillator  
and low-level feedback circuitry, peak  
detection/demodulation circuit, a com-  
parator and two complementary output  
stages.  
lated waveform as input to the com-  
parator. The comparator sets the states  
of the complementary outputs by com-  
paring the input from the demodulator  
to an internal reference. External loads  
are required for the output pins.

over Temperature  
The oscillator, along with an external  
LC network, provides controlled oscilla- A transient suppression circuit is  
tions where amplitude is highly depen-  
dent on the Q of the LC tank. During  
low Q conditions, a variable low-level

included to absorb negative transients  
at the tank circuit terminal.
