TECA1-5V-5V-D provides interface ports for users to set the desired
object temperature, i.e. set-point temperature; the maximum output voltage
across TEC; and the compensation network. The compensation network compensates
high order thermal load and thus stabilizes temperature control loop.
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.
