GENERAL 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.
●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 Programmability
●APPLICATIONS
● Thermoelectric Cooler (TEC) Temperature Control
● Resistive Heating Element Control
● Temperature Stabilization Substrate (TSS) Control
