ADN8830 is a thermoelectric cooler controller with features of high efficiency, small size, low noise, etc. It is suitable for applications such as thermoelectric cooler temperature control, resistive heating element control, temperature stabilization, etc.
The ADN8830 is a monolithic controller designed to drive a thermoelectric cooler (TEC) for temperature stabilization of laser diodes or passive components used in telecommunications equipment. It utilizes a negative temperature coefficient (NTC) thermistor for sensing and allows the target temperature to be set via an analog input voltage from a DAC or external resistor divider.
The device features a PID compensation amplifier with high stability and low noise, allowing users to adjust the network to optimize settling time. Key capabilities include programmable switching frequencies up to 1 MHz, oscillator synchronization with external signals, and various monitoring outputs for temperature and TEC voltage.
