NCD9830
8-Bit, 8-Channel ADC with
I
2
C Serial Interface
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 I
2
C interface and can also be
configured to be a single ended or differential type measurement.
Communication with the NCD9830 is accomplished via the I
2
C
interface which is compatible with industry standard protocols.
Through this interface configuration of the NCD9830 is achieved.
This allows the user to read the current measurement for the selected
channel, change to an external reference and modify the measurement
type (single ended or differential).
The NCD9830 is available in a 16−lead TSSOP package and
operates over a wide supply range of 2.7 to 5.5 V.
Features
• 8−bit ADC
• 8 Single−ended Inputs/4 Differential Inputs
• 2.7 V to 5.5 V Operation
• Built in 2.5 V Reference
• 2 Address Selection Pins
• Low Power Consumption
• I
2
C Compliant Interface − Standard, Fast and High Speed Modes
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
