ADS1115

The ADS1115 is a 16-bit precision ADC module with a programmable gain amplifier (PGA), I2C interface, and internal oscillator. It adds high-resolution analog input capability to microcontrollers that lack an ADC or need better resolution than their onboard ADC provides. Configurable as 4 single-ended or 2 differential input channels.

Features:

• Resolution: 16-bit
• Interface: I2C
• Supply voltage: 2.0V – 5.5V
• Data rate: 8 SPS – 860 SPS (programmable)
• Channels: 4 single-ended or 2 differential
• Programmable Gain Amplifier (PGA): up to ×16
• Low current: 150μA continuous, auto-off in single-shot mode
• Internal voltage reference and oscillator
• Programmable comparator with alert/ready pin
• Operating temperature: −40°C to +140°C
• Compatible with Arduino, ESP32, Raspberry Pi
