Analog Pyroelectric Detectors
Analog Pyroelectric Detectors

Broadcom offers a full range of analogue TO packaged sensors from single to quad channel in the common sized TO-39 packages. The products are reliable and easy to use. They all benefit from both the advanced performance of our thin film pyroelectric sensor and the integration of a front-end operational amplifier within the package.

Together this provides a compelling competitive advantage offering extremely strong responsivity, fast frequency of operation, faster response than any other pyroelectric or thermopile, instant switch-on, and unparalleled robustness.  The customers are setting new performance records in terms of measurement resolution, temperature range, and real-time analysis.
