# Adafruit 4-Channel ADC Breakouts

## Assembly and Wiring

# Assembly:
The board comes with all surface-mount parts pre-soldered. &nbsp;For breadboard use, the included header-strip should be soldered on:## Prepare the header strip
Cut the supplied header strip to length and insert it long-pins-down in your breadboard to hold it for soldering.![sensors_2012_11_10_IMG_0757-1024.jpg](https://cdn-learn.adafruit.com/assets/assets/000/002/576/medium640/sensors_2012_11_10_IMG_0757-1024.jpg?1396784735)

## Position the breakout&nbsp;board
Place the breakout board on the header pins.![sensors_2012_11_10_IMG_0759-1024.jpg](https://cdn-learn.adafruit.com/assets/assets/000/002/577/medium640/sensors_2012_11_10_IMG_0759-1024.jpg?1396784744)

## Solder!
Solder each pin for a good electrical connection.  
![sensors_2012_11_10_IMG_0761-1024.jpg](https://cdn-learn.adafruit.com/assets/assets/000/002/578/medium640/sensors_2012_11_10_IMG_0761-1024.jpg?1396784751)

# Wiring:

## Power
First connect VDD and GND. &nbsp;These boards will work with either a 3.3v or a 5v supply. &nbsp;The diagram below shows connection to the Arduino 5v pin.  
Danger:

## I2C Connections
I2C requires just 2 pins to communicate. &nbsp;These can be shared with other I2C devices. &nbsp;For R3 and later Arduinos (including MEGA and DUE models), connect SDA-\>SDA and SCL-\>SCL.![](https://cdn-learn.adafruit.com/assets/assets/000/002/674/medium800/sensors_ADC_i2c_bb-1024.jpg?1396785691)

## I2C "Classic"
For older Arduino boards without dedicated SDA and SCL pins, connect as shown below. &nbsp;(For older Arduino Megas, SDA and SCL are on pins 20 and 21)![](https://cdn-learn.adafruit.com/assets/assets/000/002/675/medium800/sensors_ADC_Classic_i2c_bb-1024.jpg?1396785699)

## I2C Addressing

The ADS11x5 chips have a base 7-bit I2C address of 0x48 (1001000) and a clever addressing scheme that allows four different addresses using just one address pin (named **ADR** for ADdRess). To program the address, connect the address pin as follows:

![](https://cdn-learn.adafruit.com/assets/assets/000/112/700/medium800/arduino_compatibles_addrPin.png?1656448546)

The following diagram shows one board addressed as 0x48:

![](https://cdn-learn.adafruit.com/assets/assets/000/002/676/medium800/sensors_ADC_Address_0_bb-1024.jpg?1396785706)

## Multiple Boards
By assigning each board a different address, up to 4 boards can be connected as below:![](https://cdn-learn.adafruit.com/assets/assets/000/002/677/medium800/sensors_FourBoards_bb-1024.jpg?1396785716)
