CS209A
Description
The CS209A is a bipolar monolithic
integrated circuit for use in metal detec-
tion/proximity sensing applications.
The IC (see block diagram) contains two
on-chip current regulators, oscillator
and low-level feedback circuitry, peak
detection/demodulation circuit, a com-
parator and two complementary output
stages.
The oscillator, along with an external
LC network, provides controlled oscilla-
tions where amplitude is highly depen-
dent on the Q of the LC tank. During
low Q conditions, a variable low-level
feedback circuit provides drive to main-
tain oscillation. The peak demodulator
senses the negative portion of the oscil-
lator envelop and provides a demodu-
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.
A transient suppression circuit is
included to absorb negative transients
at the tank circuit terminal.
