Overview

Instruments requiring TEC temperature control

GENERAL DESCRIPTION The ADN88331 is a monolithic H-bridge TEC driver with integrated 1 A power MOSFETs. It has a linear power stage with the linear driver (LDR) output and a pulse-width modulation (PWM) power stage with the SW output. Depending on the control voltage at the CONT input, the ADN8833ACBZ-R7 drives current through a TEC to settle the temperature of a laser diode or a passive  component attached to the TEC module to the programmed target temperature.  The control voltage applied to the CONT input is generated by a digital-to-analog converter (DAC) closing the digital proportional, integral, derivative (PID) loop of temperature control system. The internal 2.5 V reference voltage provides a 1% accurate output that is used to bias a voltage divider network to program the maximum TEC current and voltage limits for both the heating and cooling modes. It can also be a reference voltage for the DAC and the temperature sensing circuit, including a thermistor bridge and an analog-to-digital converter (ADC).
