PY-ITV-SINGLE–T046(3+1)

SINGLE CHANNEL
PYROELECTRIC DETECTOR
Introduction
The Pyreos thin film pyroelectric gas
detectors
offer
exceptionally
high
responsivity, low microphonics and class
leading thermal and electrical stability.
This high performance is now available in
the miniaturized TO46 form but retains an
excellent signal to noise ratio, and offers a
fast, stable response over a wide
operating frequency range. The sensor
element is built into a low noise circuit that
has an internal cmos op amp, with a 10 G
Ohm feedback resistor outputting an
industry standard voltage mode signal.
The standard pin-out makes it a simple
replacement for leading voltage mode
devices.
