Built -in EEPROM The input code and configuration information that can be used to store DACs are suitable for applications that need to save DAC device settings during power off although EEPROM can save settings, it has limited number of writing times, generally about 20,000 times. Support I2C serial interface support standards 100kbps, fast 400kbps, and high -speed 3.4Mbps integrated 4.7k pull -up resistance, connecting multiple devices on the same I2C bus, you need Value to ensure the stability of I2C communication. Increase the external A0 address pins When the system needs to use multiple MCP4725 modules, you can avoid the address conflict by setting different A0 pin levels. At most eight available addresses can be provided.

ADS1115 16 Bit Analog-to-Digital-Converter It features high accuracy, programmable gain amplifier PGA, four differential input channels, and internal oscillator for a variety of measurement and control applications.. Supply voltage2.7V5.5V.. Programmable Gain Amplifier PGA The gain of the input signal can be adjusted in steps of 12, 14, 18 or 116. This makes it suitable for applications with different input signals.. Four differential input channels Four differential signals can be sampled simultaneously. In addition, it also supports single-ended inputs, which can sample a single-ended signal.. Internal oscillator The frequency can be set by an external resistor. This allows it to be used for applications with different frequencies..

TCA9548A I2C IIC 8 Channel Expansion Board Specifically designed to resolve the conflict of I2C device addresses, you can expand eight I2C interface devices with the same address on the main control board and use them normally. Working Voltage 1.65-5.5V. Interface I2C IIC. Selectable I2C address 0x700x77. Max Clock Frequency 400KHz.
