DESCRIPTION

The ADS1115-Q1 is a precision analog-to-digital

23

•

WIDE SUPPLY RANGE: 2.0V to 5.5V

converter (ADCs) with 16 bits of resolution offered in

•

LOW CURRENT CONSUMPTION:

an ultra-small, leadless QFN-10 package or an

Continuous Mode: Only 150

μA

MSOP-10 package. The ADS1115-Q1 is designed

Single-Shot Mode: Auto Shut-Down

with precision, power, and ease of implementation in

mind.
