Overview
The ADN8830ACPZ-REEL, manufactured by Analog Devices Inc., is a specialized power management IC designed to control thermoelectric coolers (TECs). This monolithic controller is used to stabilize the temperature of components such as laser diodes or passive components 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.
