The LHi 1148 pyroelectric infrared detector is designed for high end PIR
alarm applications. It includes a Quad type pyroelectric ceramic with 4
sensitive elements connected to two FET source follower circuits. Thus it
provides for dual channel output . One channel is inverse to the other.
The LHi 1148 detector is available in TO-5 housing with standard infrared
filter. It offers excellent common mode performance (match) and low noise.
