• Description: Smallest TEC Power Drivers
• Manufacturer: Maxim Integrated Products

6) To ensure high DC-loop gain and minimum loop
error, keep the board layout adjacent to the negative
input pin of the integrator (U2 in Figure1) clean and free
of moisture. Any contamination or leakage current into
this node can act to lower the DC gain of the integrator
which can degrade the accuracy of the thermal loop. If
space is available, it can also be helpful to surround the
negative input node of the integrator with a grounded
guard ring.
