2.7V Dual Channel 12-Bit A/D Converter with SPI Serial Interface, Microchip, SOIC8, RoHS

The TEC1-12704 Peltier cell with a cooling capacity of 45 W and dimensions of 40×40×4.0 mm enables efficient cooling at 12 V and 4 A. Thanks to its wide operating temperature range, it is suitable for use in electronics cooling systems, laboratory equipment, and compact refrigerators.

The module protects the load against reverse polarity to -60 V, but does not block reverse current, which is desirable in applications such as motor control. It uses the LM74500-Q1 controller and a MOSFET transistor. Thanks to its low impedance (1.5 mΩ), it supports currents up to 25 A continuous and 50 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5387
