Overview
The ADN8830ACPZ is a thermoelectric cooler (TEC) controller integrated circuit designed by Analog Devices Inc. This monolithic controller is specifically engineered to stabilize the temperature of components such as laser diodes or passive components used in telecommunications equipment. It utilizes a negative temperature coefficient (NTC) thermistor to sense the temperature of the object attached to the TEC and adjusts the temperature based on an analog input voltage from a DAC or an external resistor divider.
