I2C ADS1115 16 Bit ADC 4 Channel Module With Programmable Gain Amplifier Board

Description For microcontrollers without an analog to digital converter or when you want a higher precision ADC the ADS1115 provides 16 bit precision at 860 samples second over I2C The chip can be configured as 4 single ended input channels or two differential channels As a nice bonus it even includes a programmable gain amplifier up to x16 to help boost up smaller single differential signals to the full range We like this ADC because it can run from 2V to 5V power logic can measure a large range of signals and its super easy to use It is a great general purpose 16 bit converter The chip s fairly small so it comes on a board with ferrites to keep the AVDD and AGND quiet Interfacing is done via I2C The address can be changed to one of four options see the datasheet table 5 so you can have up to 4 ADS1115 s connected on a single 2 wire I2C bus for 16 single ended inputs Feature Wide supply range 2 0V to 5 5VLow current consumption Continuous Mode Only 150uA Single Shot Mode Auto Shut DownProgrammable data rate 8SPS to 860SPSInternal Low drift voltage referenceInternal oscillatorInternal PGAI2C interface Pin Selectable AddressesFour Single ended or two differential inputsProgrammable comparatorThis board chip uses I2C 7 bit addresses between 0x48 0x4B selectable with jumpersPackage included 1 x I2C ADS1115 16 Bit ADC 4 Channel Module
