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: ؎0.01؇C

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.
