MCP4725 max 100Hz output - can frequency be increased?

2024-07-11 20:31:10 The MCP4725 uses I2C to communicate with the controller. When using traditional controllers such as the Arduino, the fastest mode, Fast (400kbps), can only be used. Under such transfer speed, DAC module can barely reached 100 Hz. The MCP4725's I2C supports high-speed mode, High-speed (3.4Mbps), but most of the mainstream controllers does not support this I2C mode. In sum, limited by the communication interface, the output frequency is difficult to be further improved. Tonny12138
