PY-LA-S-128 (Rev. 1.3) Thin Film Pyroelectric Linear 128 Element Line Sensor Array With Integrated Read-Out Electronics Introduction The Pyreos line sensor array utilises our unique thin-film pyroelectric PZT material to offer class leading resolution and performance across a wide wavelength range at a very affordable price. The ASIC readout electronics output is a multiplexed, amplified and filtered analogue signal for each sensor element. The sensor is housed in a low profile hermetic metal package along with a temperature sensor, and is fitted with a linear variable filter or a broadband filter.

DVDD Operating voltage (+5 V) Note: Pixel 1 is nearest pin 1 of the device. Circuit Diagram The amplification circuit consists of low-noise preamplifiers for each individual sensor elements, analogue switches and an output amplifier. The pre-amplifiers transform the signal charges measured at each sensor element into a conditioned voltage. The amplified signal is then passed to sample and hold, multiplexer output buffer for the read-out process. The digital inputs are CMOS compatible. A 10k NTC thermistor is integrated within the package to monitor the line sensor temperature. Thermistor is NTC, 1%. For more details check ERTJZEG103FA Datasheet on Industrial Panasonic website.
