Thermoelectric Cooler Controller  
ADN8830  
FEATURES  
GENERAL DESCRIPTION  
High Efficiency  
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.  
Small Size: 5 mm 5 mm LFCSP  
Low Noise: <0.5% TEC Current Ripple  
Long-Term Temperature Stability: 0.01C  
Temperature Lock Indication  
Temperature Monitoring Output  
Oscillator Synchronization with an External Signal  
Clock Phase Adjustment for Multiple Controllers  
Programmable Switching Frequency up to 1 MHz  
Thermistor Failure Alarm  
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.  
Maximum TEC Voltage Programmability  
APPLICATIONS  
Thermoelectric Cooler (TEC) Temperature Control  
Resistive Heating Element Control  
Temperature Stabilization Substrate (TSS) Control  
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.
