Overview of ADS1115
The ADS1115 provides 16-bit precision at 860 samples/second over I2C for microcontrollers without an analog-to-digital converter or if you prefer a higher-precision ADC. Four single-ended input channels or two differential input channels can be installed on the chip. A configurable gain amplifier (up to x16) is included to help enhance smaller single/differential signals to the entire range. This ADC can measure a wide range of signals and runs on 2V to 5V power/logic. It’s also very straightforward to use.
Overview of ADS1015
The ADS1015 analog-to-digital converters (ADCs) are precision, low-power, 12-bit, I2Ccompatible ADCs available in an ultra-small, leadless X2QFN-10 package and a VSSOP-10 packaging. The ADS1015 converts data at speeds of up to 3300 samples per second (SPS). The PGA allows precision large- and small-signal measurements with input ranges ranging from 256 mV to 6.144 V. The ADS1015 has two modes of operation: continuous conversion and single-shot conversion.
Conclusion of ADS1115 and ADS1015
The ADS1015 is a 12-bit ADC with 4 channels, and the ADS1115 is a higher precision 16-bit ADC with 4 channels. Both have a programmable gain from 2/3x to 16x so you can amplify small signals and read them with higher precision. These two boards are very similar, differing only in resolution and speed. The ADS1115 has a higher resolution and the ADS1015 has a higher sample rate.
