8-Bit, 8-Channel ADC with I2C Serial Interface NCD9830 The NCD9830 is a two wire serially programmable analog to digital converter.

It can monitor 8 analog inputs to 8 bit resolution.

Each channel is selected using the I2C interface and can also be configured to be a single ended or differential type measurement.

Communication with the NCD9830 is accomplished via the I2C interface which is compatible with industry standard protocols.

Through this interface configuration of the NC
