Thermoelectric Cooler (TEC) Temperature Control Resistive Heating Element Control Temperature Stabilization Substrate (TSS) ControlGENERAL 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. The loop is stabilized by a PID compensation amplifier with high stability and low noise.
