MAX1978EVKIT

MAX1978EVKIT is an evaluation kit for the MAX1978. This is a fully assembled and tested PC board that implements a complete switch-mode temperature control system for a Peltier thermo-electric cooler (TEC) module. It operates from a single 3V to 5.5V supply and provides a bipolar ±2.2A (max) output to the module. A potentiometer, DAC, or external source generates a DC temperature set-point voltage. Thermal feedback from the TEC module is compared to the set-point voltage to generate the TEC current control signal. The MAX1978 controls TEC current to accurately regulate temperature. When using the DAC, the EV kit connects to the parallel port of a computer running Windows® 95, 98, or 2000. Suitable for Automated Test Equipment (ATE), EDFA optical amplifiers, fibre optic network equipment, fibre-optic laser modules, telecom fibre interfaces, WDM, DWDM laser diode temperature control applications.
