Configurable evaluation boards feature the ADN8834 TEC controller

Mouser is now stocking the Analog Devices EVAL-ADN8834 series configurable evaluation boards which feature the ADN8834 TEC controller. The boards are designed to be used with various TEC modules and thermistors. The ADN8834 TEC Controller on the evaluation boards delivers and controls bidirectional current through the TEC using two pairs of the complimentary integrated MOSFETs in an H-bridge configuration. The board's TEC cooling and heating current limits are set to 1.5A. The maximum TEC voltage is programmed to be 3V using two on-board resistor dividers. The temperature set-point circuit is optimized to work with the 10kohm NTC thermistor. The PID compensation network components are included on board. Designers can replace PID compensation network components by soldering different value components. Designers can also modify the cooling and heating TEC current limits and maximum TEC voltage setting by changing values of the corresponding components, says the company.
