ADS1115 - One of Industry's Smallest 16-bit ADCs

70% Smaller than Most Competing Devices
Now Available at Digi-Key

Texas Instruments' introduced a family of 16-bit analog-to-digital converters (ADCs) packaged in a leadless QFN package measuring 2.0mm x 1.5mm x 0.4mm – 70% smaller than most of the competition. In addition to significant system space savings, the ADS1115 family provides product options for scalable integration to reduce component count and simplify design. This family supports battery monitoring, portable instrumentation, industrial process control, smart transmitters, medical instrumentation and other industrial and consumer systems.    ADS1115 Series Datasheet

Designed for precision, power efficiency and ease of implementation, the ADS1115 family performs conversions at programmable data rates up to 860 samples per second (SPS), consuming just 150µA (typical) of supply current and operating down to 2V. The ADS1115 is the most highly integrated member of the new family, incorporating an oscillator, low-drift reference, programmable gain amplifier, comparator and four-channel input multiplexer into a tiny package. This family also includes 12-bit versions for increased flexibility.
