Features: <br>AD8495 is an easy-to-use K-type thermocouple amplifier. It will convert the small voltage generated by the thermocouple junction into signal that analog-to-digital converter (ADC) or microcontroller can easily read. The gain from the thermocouple to the amplifier output is approximately 5 mV/°C. <br>AD8495 uses on-chip temperature sensor for cold junction compensation. Thermocouples can measure in wide ambient temperature range. <br>AD8495 built-in a precision instrumentation amplifier. The amplifier has high common-mode rejection performance that can suppress common mode noise that long lead thermocouples may pick up. For extra protection, the amplifier's high-impedance input terminal allows for easily adding additional filtering. <br>AD8495 supports wide supply voltage range. Under a single 5V pwoer supply, AD8495 can cover nearly 1,000℃ thermocouple temperature range. Under 3V power supply, it can be directly cnected to low supply voltage ADC interface. It can also be power by up to ± 18V power supply, support industrial system that require wide common mode input range. <br>Regardless of the power rails, AD8495 can easily measure negative temperature. It can uses voltage on reference pin to adjust the 0℃. <br>output, which provides the flexibility for adjusting AD8495 output range to adapt ADC. <br>Stable input is designed to handle a variety of actual connection conditions. AD8495 can withstand much higher input voltage than supply rails. For example, under ± 5 V power supply, the voltage at the input, even to ±35 V, is guaranteed to not damage the device. Small and large input bias current characteristics facilitate thermocouple open circuit fault detection. <br> <br> <br>Application: <br>J or K type thermocouple <br>Oven temperature measurement <br>Exhaust gas temperature detection <br> <br>Specification: <br>Material: Electrical components <br> <br>Package List: <br>1 x Operational Amplifier Module <br>1 x Pin Header <br>1 x 2-Pin Socket<br>1、AD8495 is an easy-to-use K-type thermocouple amplifier.
