1. Introduction

ADC Click is an accessory board in mikroBus™ 

form factor. It includes a 12-bit Analog-to-

Digital Converter MCP3204 that features 50k

samples/second, 4 input channels and low-power consumption (500nA typical standby,

2µA max). Board uses SPI communication

interface. It is small in size and features

convenient screw terminals for easier

connections. Board is set to use 3.3V power

supply by default. Solder PWR SEL jumper to

5V position if used with 5V systems.

Once you have soldered the headers your

board is ready to be placed into desiredmikroBUS™ socket. Make sure to align the

cut in the lower-right part of the board

with the markings on the silkscreen at the

mikroBUS™ socket. If all the pins are aligned

correctly, push the board all the way

into the socket.

4. Reading Analog Input

There are four analog input screw ter

for each of the supported A/D channe

added two more terminals for GND refe

Each analog input voltage is conv

to appropriate 12-bit digital value,

can be read using industry standa

communication interface.

Turn the board upward again. Make sure

to align the headers so that they are

perpendicular to the board, then solder the

pins carefully.

Turn the board upside down, so that

bottom side is facing you upwards. Place

shorter parts of the header pins in the

both soldering pad locations.

Before using your click board, make sure

to solder the provided 1x8 male headers

to both sides of the board. Two 1x8 male

headers are included with the board in

the package.
