Features:

• 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.
• AD8495 uses on-chip temperature sensor for cold junction compensation. Thermocouples can measure in wide ambient temperature range.
• 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 amplifiers high-impedance input terminal allows for easily adding additional filtering.
• 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.
• Regardless of the power rails, AD8495 can easily measure negative temperature. It can uses voltage on reference pin to adjust the 0℃.
• Output, which provides the flexibility for adjusting AD8495 output range to adapt ADC.
• 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.
