PCF8591 Introduction

The PCF8591 is a single-supply, low-power 8-bit CMOS data acquisition device with 4 analog inputs, one output, and a serial I2C bus interface.
Three address pins, A0, A1, and A2, are used to program hardware addresses, allowing up to 8 devices to be connected to the I2C bus without additional hardware.

ADS1115 Introduction

The ADS1115 device is a precision, low power, 16-bit, I2C compatible analog-to-digital converter ADC that integrates a low drift voltage reference and oscillator.
The ADS1115 performs conversions at data rates up to 860 samples per second (SPS).
