Overview
The ADN8830ACPZ-REEL7 is a monolithic thermoelectric cooler (TEC) controller produced by Analog Devices Inc. This device is designed to stabilize the temperature of 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 allows for precise temperature control through an analog input voltage set by a DAC or an external resistor divider.
