4pcs ADS1115 16 Bit 4 Channel I2C IIC, MELIFE Analog-to-Digital ADC PGA Converter with Programmable Gain Amplifier High Precision ADC Converter Development Board.

High precision ADS1115 16 Bit 4 Channel Analog-to-Digital ADC Converter.
Wide Voltage Supply Range: 2.0V to 5.5V, operate in a comparator mode which is helpful for maintaining accuracy.
Continuous mode: Only 150uA is easy to implement, single mode: auto power off function, onboard reference and oscillator.
Especially a good tool for Pi, there is no analog GPIO pin; Easy to use I2C ADC Converter, with Programmable Gain Amplifier.
The ADS1115 is measured at high resolution and has an input multiplexer (MUX) that provides two programmble conparator differentials or four single-ended input; Four single-ended or ±256mV, allowing both large and small signals to be the differential input.
