RPI-ADS1115-ADC-Module

---

Description

The ADS1113, ADS1114, and ADS1115 are precision analog-to-digital converters (ADCs) with 16 bits of resolution offered in an ultra-small, 
leadless QFN-10 package or an MSOP-10 package. 
The ADS1113/4/5 are designed with precision, power, and ease of implementation in mind. 
The ADS1113/4/5  feature an onboard reference and oscillator. 
Data are transferred via an I2C-compatible serial interface, four I2C slave addresses can be selected. 
The ADS1113/4/5 operate from a single power supply ranging from 2.0V to 5.5V. 
The ADS1113/4/5 can perform conversions at rates up to 860 samples per second (SPS). 
An onboard PGA is available on the ADS1114 and ADS1115 that offers input ranges from the supply to as low as ±256mV, 
allowing both large and small signals to be measured with high resolution. 
The ADS1115 also features an input multiplexer (MUX) that provides two differential or four single-ended inputs. 
The ADS1113/4/5 operate either in continuous conversion mode or a single-shot mode that automatically powers down
after a conversion and greatly reduces current consumption during idle periods. 
The ADS1113/4/5 are specified from –40°C to +125°C.
