ADN8834 - 1.5A Thermoelectric Cooler (TEC) Controller

Description

The ADN8834 is a monolithic TEC controller with an integrated TEC controller.

It has a linear power stage, a pulse-width modulation (PWM) power stage, and two zero-drift, rail-to-rail operational amplifiers.

Features

  • Patented high efficiency single inductor architecture Integrated low RDSON MOSFETs for the TEC controller TEC voltage and current operation monitoring No external sense resistor required Independent TEC heating and cooling current limit settings Programmable maximum TEC voltage 2.0 MHz PWM driver switching frequency External synchronization Two integrated, zero drift, rail-to-rail chopper amplifiers Capable of NTC or RTD thermal sensors 2.50 V reference output with 1% accuracy Temperature lock i.
