ADS1115 16-Bit ADC Module

Description

The 4-channel 16-bit ADS1115 ADC Module is a high-precision analog-to-digital conversion solution based on the TI ADS1115IDGSR chip. This module provides four 16-bit precision analog input channels, supports both 3.3V and 5V operation, and features a hardware-configurable I2C address. The module also integrates an NTC temperature measurement interface, enabling multi-channel signal acquisition and temperature monitoring.

Features

  • High-Precision 16-bit ADC Chip: Based on the TI ADS1115IDGSR chip, it provides four 16-bit resolution analog input channels, enabling high-precision signal acquisition.
  • Flexible Input Modes: Supports 4 single-ended inputs or 2 differential inputs, suitable for various sensor signal measurement scenarios.
  • Configurable I2C Address: Configurable via the ADDR pin, supporting 4 I2C addresses to facilitate multi-device networking.
  • Wide Sampling Rate Range: Supports programmable sampling rates from 8 SPS to 860 SPS, meeting the requirements of different applications.
  • Integrated NTC Temperature Measurement Interface: Onboard MF52AT 10KΩ NTC temperature sensor interface with a B value of 3950K, ideal for temperature monitoring applications.
  • Dual-Voltage Compatible Design: Supports 3.3V/5V dual-voltage operation, with a built-in LP5907 LDO providing stable 3.3V power.
  • Automatic Level Conversion: I2C signals are automatically converted to 3.3V levels when powered by 5V, allowing direct connection to 3.3V microcontrollers.
  • Standard Interface Design: Equipped with HY2.0mm 4P connectors and 2.54mm pin headers for easy connection to various development boards.
