The OTP-667F4P is a thermopile sensor in classic TO-5 housing.
The sensor is composed of 116 elements of thermocouple in series on a floating micro-membrane having an active area of diameter 700 μm.
The thermopile sensor provides nearly Johnson-noise-limited performance, which can be calculated by its ohmic series resistance.
A thermistor element, with a lead connected to ground, is also provided inside the TO package for ambient temperature reference.
