AD8495 Thermocouple Amplifier Module

The AD8495 Thermocouple Amplifier Module is a ready-to-use circuit that provides precision amplification of thermocouple signals. It is based on the AD8495 integrated circuit, which features a built-in cold junction compensator and a high gain of 5 mV/°C. The module also includes a reference input, which can use to offset the output voltage and measure temperatures below 0°C.

AD8495 Thermocouple Amplifier Module works by amplifying the small voltage generated by a thermocouple junction. The thermocouple junction is a point where two different metals are joined together. When the temperature at the junction changes, the voltage generated by the junction also changes.

AD8495 Thermocouple Amplifier Module is a versatile and easy-to-use solution for thermocouple temperature measurement. It is suitable for a wide range of applications, including industrial process control, scientific research, and environmental monitoring.

The AD8495 Thermocouple Amplifier Module can power from a single supply voltage of 3 V to 36 V. The input voltage range is -250°C to +750°C when the module powered by 5 V, and -250°C to +410°C when the module powered by 3.3 V.

The input voltage range is determined by the gain of the AD8495 amplifier, which is 5 mV/°C. This means that for every 1 mV change in the input voltage, the output voltage will change by 5°C. The input voltage range can extend by using a reference input. The reference input is a pin on the module that can be used to offset the output voltage. This allows the module to measure temperatures below 0°C.

The reference input voltage typically set to 1.24 V. This means that when the reference input connect to ground, the output voltage will be 0°C. If the reference input connect to a positive voltage, the output voltage will be offset by that amount.

The AD8495 amplifier has a gain of 5 mV/°C. This means that for every 1 mV change in the input voltage, the output voltage will change by 5°C. The amplifier also has a built-in cold junction compensator. This compensator compensates for the voltage generated by the cold junction of the thermocouple.

The output voltage of the amplifier typically connect to an analog-to-digital converter (ADC). The ADC converts the analog voltage to a digital value, which can then read by a microcontroller or computer. The AD8495 Thermocouple Amplifier Module is a simple and effective way to measure the temperature of a thermocouple junction. It is accurate, reliable, and easy to use. Here are some of the features of the AD8495 Thermocouple Amplifier Module:
