MAX1978ETM+ Temperature Controllers for Peltier Modules

The MAX1978ETM+ series of temperature controllers are designed for Peltier thermoelectric cooler (TEC) Modules. Key features of the MAX1978ETM+ design include the addition of on-chip power FETs and thermal control-loop circuitry as to reduce the number of external components used, small component size and the reduction of noise. The on-chip instrumentation amplifier is able to interface to an NTC/PTC thermistor, thermocouple and temperature sensor.
The MAX1978ETM+ temperature controllers are suited to fibre optic and laser-diode temperature control applications.
