AD8495ARMZ-R7 - Brand New Analog Devices Sensor and Detector Interfaces
-
Description
The AD8494/AD8495/AD8496/AD8497 is a series of precision instrumentation amplifiers with thermocouple cold junction compensators on an integrated circuit. They provide a high level output of 5 mV/°C directly from a thermocouple signal by combining an ice point reference with a precalibrated amplifier. They can be used as standalone thermometers or as switched output setpoint controllers using a fixed or remote setpoint control. The AD8494/AD8495/AD8496/AD8497 can be powered from a single-ended supply and measure temperatures below 0°C by offsetting the reference input. They are equipped with thermocouple break detection and have been laser wafer trimmed to a 1°C initial accuracy and 0.025°C/°C ambient temperature rejection.
