The OTP-678D4 is a thermopile sensor in classic TO-46 housing.
The sensor is composed of 112 elements of thermocouple in series on a floating micro-membrane having an active area of 0.5mm2.
The thermopile sensor provides nearly Johnson-noise-limited performance, which can be calculated by its ohmic series resistance.
A thermistor with a lead connected to ground, is also provided inside the TO package for ambient temperature reference.
