FEATURES
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 150μA
MSOP-10 package. The ADS1115-Q1 is designed
Single-Shot Mode: Auto Shut-Down
with precision, power, and ease of implementation in
mind. The ADS1115-Q1 feature an onboard
• PROGRAMMABLE DATA RATE:
reference and oscillator. Data are transferred via an
8SPS to 860SPS

VOLTAGE REFERENCE
operates from a single power supply ranging from
• INTERNAL OSCILLATOR
2.0V to 5.5V.
• INTERNAL PGA
The ADS1115-Q1 can perform conversions at rates

C™ INTERFACE: Pin-Selectable Addresses
up to 860 samples per second (SPS). An onboard
PGA is available on the ADS1115 that offers input
• FOUR SINGLE-ENDED OR TWO
ranges from the supply to as low as ±256mV,
DIFFERENTIAL INPUTS
allowing both large and small signals to be measured
• PROGRAMMABLE COMPARATOR
with high resolution. The ADS1115 also features an
input multiplexer (MUX) that provides two differential
APPLICATIONS
or four single-ended inputs.
• AUTOMOTIVE APPLICATIONS
The ADS1115-Q1 operate either in continuous
conversion mode or a single-shot mode that
• PORTABLE INSTRUMENTATION
automatically powers down after a conversion and
• CONSUMER GOODS
greatly reduces current consumption during idle
• BATTERY MONITORING
periods. The ADS1115-Q1 is specified from –40°C to
• TEMPERATURE MEASUREMENT
+125°C.
