PY-LAS-128+1 (Rev. 1.3) Thin Film Pyroelectric Linear 128+1 Element Line Sensor Array With Integrated Read-Out Electronics Introduction The Pyreos line sensor array (Linear Array) utilises our unique thin-film pyroelectric PZT material to offer class leading resolution and performance across a wide infrared 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 the customers choice of filter window. An additional +1 sensor element provides higher sensitivity on a discrete wavelength, e.g. for lubrication oil or foodstuffs. The +1 sensor is located for ATR and transmission use.

DVDD Operating voltage (+5 V) Circuit Diagram 128 Array Readout 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.
