This is a HAL based library for I²C MCP4725 12-bit Digital-to-Analog Converter with EEPROM. This library has been ported from this Arduino library to STM32 using HAL drivers.
- operating/reference voltage 2.7v - 5.5v
- output voltage from 0 to operating voltage
- maximum output current 25mA
- output impedance 1 Ohm
- maximum output load 1000pF/0.001μF in parallel with 5 kOhm
- voltage settling time 6 μsec - 10 μsec
- slew rate 0.55 V/μs
- add 100μF & 0.1 μF bypass capacitors within 4mm to Vdd
- device has 14-bit EEPROM with on-chip charge pump circuit for fail-safe writing
- estimated EEPROM endurance 1 million write cycles
- if Vdd < 2v all circuits & output disabled, when Vdd increases above Vpor device takes a reset state & upload data from EEPROM
Supports all MCP4725 features:
- Fast write
- Register read & write
- EEPROM read & write
- Power down
- General reset
- General wake-up
Is it helpfull?
This section will be completed asap
