Description

This multi-function I2C device includes a MCP23017 configured for 8-Channels of Open Collector Output (Up to 100ma per Channel) and 8-Bit General Purpose Programmable Input and Outputs. Open Collector outputs can be used to directly control mechanical relays or other low-power devices. On-Board LEDs indicate the On/Off status of each Open Collector output.

 

This device also includes a ADS7828 8-channel analog-to-digital converter (ADC) with 12-bit resolution per channel. This device contains a sample-and-hold amplifier that captures and locks the analog signal value at a constant level for a specific period of time.

The ADS7828 also features an internal, asynchronous circuit--meaning it does not follow a clock signal and the state of the circuit changes as soon as the input changes. The device has a 50kHz sampling rate and its I2C interface supports standard, fast, and high speed modes.

 

On-Board address jumpers allow you to define the start address range of each I2C chip. Up to 4 ADS7828 chips are supported per I2C port and up to 8 MCP23017 chips are supported per I2C port.

All analog and digital Inputs are designed for 5V operation (higher voltages will damage the on-board chip set).

May be powered by the I2C bus or powered externally (jumper-selectable).
