8-Channel I2C 0-24V Analog To Digital Converter ADC with I2C Interface
- 8 Channel ADC with 16-Bit Resolution
- Input Voltage Range 0 to 24V DC
- Programmable x1-x8 Gain Amplifier
- Up to 4 Devices per I2C Port
- Up to 3.4MHz Communication Speed
- 0x68 Start Address

This Analog to Digital Converter Board is capable of reading 0-24V input voltage. It has an onboard Amplifier for signal conditioning. This Board uses two MCP3428 to read the amplified Signal. The MCP3428 is a 4-Channel Analog to Digital Converter with 16-Bit resolution, ideally suited for low-speed high-resolution sensor monitoring. The MCP3428 is capable of reading analog voltages at 15 samples per second with 16-Bit resolution or 240 samples per second at 12-bit resolution. The MCP3428 has an x1, x2, x4, x8 programmable gain amplifier, making it an ideal choice for monitoring extremely low-voltage sensors. All 8 channels are capable of monitoring a full-scale range of 0-24V. Up to 8 MCP3428 devices are capable of sharing a single I2C communication port, using three floating address inputs.
This 0 to 24V Analog to Digital Converter board has two MCP3428 onboard, so to use all 2 MCP3428 at the same time you will need to set them each up at a different address. This Analog to Digital Converter board has onboard jumpers to select the different addresses for both of the MCP3428.
Note: Set MCP3428 gain at one to read 0-24V Signal and set the gain at two to read 0-5V Signal.
