Driving TECs (Peltier coolers) to precisely regulate object temperature.
Regulates object temperature by both cooling and heating through a TEC (Peltier); can also drive a resistive heater.
Suitable for temperature control in vacuum environments.

Description
The TEC5V6A-D is an electronic module designed for driving TECs (Thermo-Electric Coolers) with high stability in regulating the object temperature, high energy efficiency, zero EMI, and small package.
The module is housed in a 6-sided metal enclosure that shields electromagnetic interference (EMI), preventing the controller and the surrounding electronics from interfering with each other. It can also be used in a vacuum environment.
It provides these functions: thermistor T-R curve linearization, temperature measurement and monitoring, temperature control loop status indication, TEC voltage monitoring, power up delay, and shut down.
The TEC5V6A-D comes with a high stability low noise 3.0V voltage reference which can be used for setting the desired object temperature by using a POT (Potentiometer) or a DAC (Digital to Analog Converter). When using this reference for setting the set-point temperature, the set-point temperature error is independent of this reference voltage.

Choosing a Variant
All variants are 6A, DIP-package controllers; they differ mainly in their maximum |VTEMP − VTEMPSP| (temperature-control tightness): -D ≤ 5mV, -DA ≤ 2mV, -DAH ≤ 0.5mV. -NT ships without an internal temperature-range setting network. Prototyping and compensation-network tuning can be done on the TECEV104 evaluation board.
Suffix Definition:
-D: For example: TEC5V6A-D. The controller comes with DIP package.
A: For example: TEC5V6A-DA. Maximum|VTEMP − VTEMPSP| is ≤ 2mV.
H: For example: TEC5V6A-DAH. Maximum|VTEMP − VTEMPSP| is ≤ 0.5mV.
-NT: For example: TEC5V6A-NT. There is no internal temperature range setting network.
