The ADN8834WACPZ is a single-chip TEC controller with an integrated TEC controller. It includes a linear power stage, a pulse width modulated (PWM) power stage and two zero-drift, rail-to-rail operational amplifiers. The linear controller operates with a PWM driver to control the internal power MOSFET in an H-bridge configuration. by measuring the thermal sensor feedback voltage and using the integrated op-amp as a proportional-integral-derivative (PID) compensator to condition the signal, the ADN8834 builds up the temperature of the laser diode or passive component connected to the TEC module via the TEC drive current to a programmable target temperature.
