AFE539A4 Evaluation Module
Description
The AFE539A4EVM is a development board designed
to evaluate the performance of the AFE539A4. The
AFE539A4 is a device with integrated state machine
configured as proportional-integral (PI) controller and
ADC for real-time closed-loop control of applications
such as thermoelectric cooling (TEC). The device
contains advanced features such as Hi-Z output
mode at power down, overcurrent sensing and
protection and a non-volatile memory (NVM) to store
configurations. This device allows for processor-less
applications and design reuse of real-time closed loop
systems.

1.4 Device Information The AFE539A4 is a 10-bit, 4-channel DAC device where one of the channels can be configured as a 10-bit ADC input for analog sensing. The device contains an integrated state machine that is configured as a PI controller. - Page 3 C, and SPI signals from the AFE signals while the AFE is running in stand-alone mode. The default hardware is set up per AFE539A4 recommended configuration guidelines. The AEN pin is connected to VDD with a pull-up resistor to hardware enable the ADC.
