FEATURES  
DESCRIPTION  
The ADS1115-Q1 is a precision analog-to-digital  
converter (ADCs) with 16 bits of resolution offered in  
an ultra-small, leadless QFN-10 package or an  
MSOP-10 package. The ADS1115-Q1 is designed  
with precision, power, and ease of implementation in  
mind. The ADS1115-Q1 feature an onboard  
reference and oscillator. Data are transferred via an  
I2C-compatible serial interface; four I2C slave  
addresses can be selected. The ADS1115-Q1  
operates from a single power supply ranging from  
2.0V to 5.5V.

The ADS1115-Q1 can perform conversions at rates  
up to 860 samples per second (SPS). An onboard  
PGA is available on the 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.

CONSUMER GOODS  
The ADS1115-Q1 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 ADS1115-Q1 is specified from –40°C to  
+125°C.
