16-Bit 4-Channel ADC ADS1115 with Programmable Gain Amplifier: a precise, powerful and versatile A/D converter
The main purpose of the ADS1115 16-Bit 4-Channel ADC is to serve as a low-consumption, powerful and accurate analogue-to-digital converter that can be adapted to perform different conversions.
It therefore has an excellent maximum data throughput (860 SPS), and can also be programmed for a much lower rate. The internal programmable gain amplifier allows you to adjust your measurements according to the signal intensity by decreasing or increasing the supply voltage (from 256 mV).
The supply ranges between 2 and 5.5 V and allows you to adapt your chosen microcontroller, for example an Arduino or Raspberry Pi. Regarding the transmission channels, these can be used as single-ended input channels (4) or differential channels (2). Finally, the I2C interface allows you to select up to 4 slave addresses, and therefore to connect 4 16-Bit ADCs to your microcontroller simultaneously!
Uses for the 16-Bit 4-Channel ADC ADS1115 with Programmable Gain Amplifier
This converter will of course prove useful to all those not possessing a microcontroller with an analogue-to-digital converter. It can also be added to a pre-existing CAN for taking more precise measurements of small and large signals.
Such a device can be used to create a temperature measuring tool, an automation or process control system, or even a battery level indicator. Its tiny size means it can be used in extremely compact portable projects.
