Difference between ADS1115 and ADS1015 ADS1115 VS ADS1015[Video]

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.

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.

Any microprocessor-based project can benefit from the high-resolution analog to digital conversion provided by the ADS1115 and ADS1015 4-channel breakout boards. These boards can operate with power and logic signals ranging from 2 to 5 volts, making them compatible with most 3.3v and 5v CPUs. The same 2-wire I2C bus can operate up to four of these boards, giving you up to 16 single-ended or differential channels. For tiny signals, a programmable gain amplifier can offer up to x16 gain.

The resolution of ADS1115 is 16 Bits, while the resolution of ADS1015 is 12 Bits. The Programmable Sample Rate of ADS1115 is 8 to 860 Samples/Second, while the Programmable Sample Rate of ADS1015 is 128 to 3300 Samples/Second. Those are the differences between them.

The ADS1015 and the ADS1115 both have a programmable gain from 2/3x to 16x so you can amplify small signals and read them with higher precision. The ADS1015  is a 4-channel 12-bit ADC, while the ADS1115  is a 16-bit ADC  with greater precision. Both feature a configurable gain range of 2/3 to 16 times, allowing you to amplify small signals and read them more precisely. These two boards are nearly identical, with the exception of resolution and speed. The ADS1115  has a greater resolution and a faster sampling rate than the ADS1015.
