ADN8830ACPZ-REEL7

热电冷却器控制器 Thermoelectric Cooler Controller

GENERAL DESCRIPTION

The ADN8830 is a monolithic controller that drives a thermoelectric cooler TEC to stabilize the temperature of a laser diode or a passive component used in telecommunications equipment.

This device relies on a negative temperature coefficient NTC thermistor to sense the temperature of the object attached to the TEC. The target temperature is set with an analog input voltage either from a DAC or an external resistor divider.
