AD8495 Thermal Precision Full K-Type Thermocouple Amplifier Module

AD8495 AD8495ARMZ Thermal Precision Full K-Type Thermocouple Amplifier Output w/ Cold Junction Compensation Module The AD8494/AD8495/AD8496/AD8497 are precision instrumentation amplifiers with thermocouple cold junction compensators on an integrated circuit. They produce a high level (5 mV/°C) output 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 either a fixed or remote setpoint control. Highlights Complete, precision laser wafer trimmed thermocouple signal conditioning system in a single IC package. Flexible pinout provides for operation as a setpoint controller or as a standalone Celsius thermometer. Rugged inputs withstand 4 kV ESD and provide over-voltage protection (OVP) up to VS ± 25 V. Differential inputs reject common-mode noise on the thermocouple leads. Reference pin voltage can be offset to measure 0°C on single supplies. Available in a small, 8-lead MSOP that is fully RoHS compliant. Features: - Low cost and easy to use - Pretrimmed for K type thermocouples - Internal cold junction compensation - High impedance differential input - Standalone 5 mV/°C thermometer - Reference pin allows offset adjustment - Thermocouple break detection - See data sheet for additional features. Applications - K type thermocouple temperature measurement - Setpoint controller - Celsius thermometer - Universal cold junction compensator - White goods (oven, stove top) temperature measurements - Exhaust gas temperature sensing - Catalytic converter temperature sensing
