Details

GENERAL DESCRIPTIONThe 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. 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.FEATURES High Efficiency Small Size: 5 mm x 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 Maximum TEC Voltage ProgrammabilityAPPLICATIONS Thermoelectric Cooler (TEC) Temperature Control Resistive Heating Element Control Temperature Stabilization Substrate (TSS) Control
