LTC2057 Differential Thermocouple Amplifier

Dec 9th 2003
The LTC2057 is a high voltage, low noise, zero-drift operational amplifier that offers precision DC performance over a wide supply range of 4.75V to 36V or 4.75V to 60V for the LTC2057HV. Offset voltage and 1/f noise are suppressed, allowing this amplifier to achieve a maximum offset voltage of 4μV and a DC to 10Hz input ...

LTC6081/LT1025 Type K Thermocouple Signal Conditioner with ±350V Protection from Accidental Contact and Cold Junction Compensation

Dec 9th 2003
A high input impedance amplifier permits the use of large valued input resistors and retains signal accuracy. This is very useful for protecting both the amplifier and cold junction compensator in thermocouple applications as the sense element can often be inadvertently connected to destructive voltage potentials. The 1MΩ ...

Type K Thermocouple 10mV/°C Thermometer with Positive Output

Dec 9th 2003
The LT1025 is a micropower thermocouple cold junction compensator for use with type E, J, K, R, S, and T thermocouples. It utilizes wafer level and post-package trimming to achieve 0.5°C initial accuracy. Special curvature correction circuitry is used to match the “bow” found in all thermocouples so that accurate ...
