The I2C-ADC board is a 14-pin CMOS
device that provides 8-CH, 12-bit of
Analog to Digital Converter (ADC) using
I
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
converter.
This board features innovations that set it
apart from other ADC module. Innovations
feature like on-board I
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 I
channel multiplexer. The Analog-to-Digital
(A/D) converter features a sample-and-
hold amplifier and internal, asynchronous
clock. The combination of an I
wire
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 I
address and allow up to four devices to
share the same I
channels.
