Why will the MCP4725 DAC's EEPROM wear out after 20,000 write operations? What does that even mean?
Before I get to the question, let me give you some background info.
I'm trying to make a digitally controlled power supply. I'm going to use an MCP4725 DAC to set the reference voltage for the power supply. The DAC will be controlled by an STM32…

Why does MPC4725 DAC output in range 0-3.3V when VREF is 5V?
I am trying to produce a 0-5V variable output from a Raspberry Pi using:
adafruit MCP4725 DAC breakout (https://www.adafruit.com/product/935)
SparkFun PCA9306 level translator breakout (https://www.sparkfun.com/products/15439) to shift between the…

What does the MCP4725 Power-On-Reset (POR) value indicate?
I managed to read from an MCP4725 using I2C. In the second byte below, the POR value it gives me is '1' (the whole byte is 11000000)
I know that if RDY/BSY = 1, it means the device is ready to write its EEPROM.
When does POR = 0? What does it mean…
