Specifications
Description
The LD209A (analog CS209A) is a bipolar monolithic integrated circuit for use in
metal detection/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 comparator and
two complementary output stages.
The oscillator, along with an external LC network, provides controlled oscillations
where amplitude is highly dependent on the Q of the LC tank. During low Q conditions,
a variable low-level feedback circuit provides drive to maintain oscillation. The peak
demodulator senses the negative portion of the oscillator envelop and provides a
demodulated waveform as input to the comparator. The comparator sets the states of
the complementary outputs by comparing 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.
Features
● Separate Current Regulator for Oscillator
