ADS1015 12-Bit ADC - 4 Channel with Programmable Gain Amplifier - STEMMA QT / Qwiic

The ADS1015 is a high-precision 12-bit analog-to-digital converter (ADC) providing 3300 samples per second over an I2C interface. It features 4 single-ended input channels or 2 differential channels along with a programmable gain amplifier (PGA) up to x16 to amplify smaller signals for full-range measurement.

The breakout board operates over a wide voltage range from 2.0V to 5.5V and is compatible with various microcontrollers that lack onboard ADC or require higher accuracy. Equipped with ferrites for noise reduction on AVDD and AGND lines, it utilizes the STEMMA QT / Qwiic form factor for easy, solderless connection with compatible quick-connect cables.

This board is ideal for general-purpose ADC needs with low power consumption, multiple programmable data rates (128 SPS to 3.3 kSPS), an internal low-drift voltage reference, internal oscillator, and programmable comparator functionality.
