MINIATURE FOUR CHANNEL
PYROELECTRIC DETECTOR
Introduction
Unlike other pyroelectric materials, the
Pyreos thin film pyroelectric sensors can
be reduced in physical size without any
reduction in sensitivity, allowing Pyreos to
offer a unique, highly stable miniaturised
four element detector in TO5 package.
This current mode high response detector
offers excellent performance in a small
footprint and at low cost. The four channel
detector uses two internal cmos dual
channel transimpedance amplifiers, with
10G feedback resistors and 0.5pF
capacitors within a current mode circuit
design. A range of IR filters are available,
or we can fit your filters to customize the
product to your specific requirements.
