PI Temperature Control Amplifier for Thermoelectric Cooler (TEC) Driver
https://www.electronics-lab.com/project/pi-temperature-control-amplifier-for-thermoelectric-cooler-tec-driver/
This is a simple Proportional, Integral (PI) temperature control amplifier. A complete thermoelectric cooler (TEC) controller can be created using this PI amplifier and OPA569 Power Op-Amp or other output amplifiers such as DRV591, DRV592 and DRV593. Proportional-integrator compensation is simpler to adjust and often provides an adequate thermal transient response to the TEC driver […]
Precision Thermocouple Amplifiers with Cold Junction Compensation – Temperature Range −25°C to +400°C
https://www.electronics-lab.com/project/precision-thermocouple-amplifiers-with-cold-junction-compensation-temperature-range-%e2%88%9225c-to-400c/
This Thermocouple Amplifier project provides a simple, low-cost solution for measuring thermocouple temperature. This board simplifies many of the difficulties of measuring thermocouples output. An integrated temperature sensor performs cold junction compensation. A fixed-gain instrumentation amplifier amplifies the small thermocouple voltage to provide a 5 mV/°C output. The high common-mode rejection of the amplifier blocks […]
