GENERAL DESCRIPTION
The ADN8830 is a monolithic controller that drives a thermo-
electric 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. The compensation network can be
adjusted by the user to optimize temperature settling time. The
component values for this network can be calculated based on
the thermal transfer function of the laser diode or obtained
from the lookup table given in the Application Notes section.
Voltage outputs are provided to monitor both the temperature of
the object and the voltage across the TEC. A voltage reference
of 2.5 V is also provided.
