What are the key features of the ADS1115?

It supports up to 860 SPS, has a flexible input multiplexer (4 single-ended or 2 differential), and includes a programmable digital comparator for threshold alerts.

How is the ADS1115 configured?

The device is configured via an I2C-compatible serial interface, allowing users to set data rates, gain, and comparator thresholds.

What should engineers review before using the ADS1115?

Engineers should review the input impedance characteristics, as the switched-capacitor input stage can affect measurement accuracy with high-impedance sources.

What is the supply voltage range for the ADS1115?

The ADS1115 operates from a single power supply ranging from 2.0V to 5.5V.

What should sourcing teams check before buying ADS1115IDGSR?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: high_availability.

What is the pinout of ADS1115IDGSR?

Use the ADS1115IDGSR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about ADS1115IDGSR pinout to locate pins, power rails, and interface signals before layout.
