I2C-ADC^TM I²C 12-Bit, 8-CH ANALOG-TO-DIGITAL
CONVERTER User Manual
Description
The I2C-ADC board is a 14-pin CMOS
device that provides 8-CH, 12-bit of
Analog to Digital Converter (ADC) using
I²C bus. There are no external
components required. Only two signal
lines SDA and SCL plus supply voltage
and ground are required to be connected.
This makes it perfect for embedded
systems that require analog-to-digital
converter.
This board features innovations that set it
apart from other ADC module. Innovations
feature like on-board I²C address jumpers,
pull-up resistors, power LED and 2.5V
reference. The module can be quickly
connected directly on to the breadboard.
The board is small and compact in size
0.70 x 0.70 inches.
The I2C-ADC is designed base on
ADS7828 IC. It is a single-supply, low-
power, 12-bit data acquisition device that
features a serial I²C interface and an 8-
channel multiplexer. The Analog-to-Digital
(A/D) converter features a sample-and-
hold amplifier and internal, asynchronous
clock. The combination of an I²C serial, 2-
wire interface and micropower
consumption makes the
I2C-ADC ideal for applications requiring
the A/D converter to be close to the input
source in remote locations and for
applications requiring isolation.
Two jumper pins vary the fixed I²C
address and allow up to four devices to
share the same I²C bus. That is total of 32
channels.
