Adafruit 1083 4-channel ADC Analogue to Digital Converter I2C

These Adafruit 4-channel ADCs can be used as either 2 x differential or 4 x single ended channels, and have a programmable pre-amp (up to 16x). These little breakout boards have built-in noise suppression to keep the supply lines clean. They uses one of four possible I2C addresses allowing you to run 4 x boards on the same 2-wire bus. Sample code is available for Raspberry Pi or Arduino.

Two ADC boards are available, 75-0562 which has 12-bit precision at up to 3300 samples per second and 75-0564 which has 16-bit precision at up to 860 samples per second.

• Supply voltage from 2 to 5.5V
• Programmable data rate
• 4 x single ended or 2 x differential channels
• Programmable gain amplifier for small signals
• Uses I2C addresses 0x48 to 0x4B, jumper selectable
