ADS1115 analog-to-digital converter 4-channel high-precision 16-bit ADC data acquisition module I2C communication

Description

• The main chip of the module adopts TI’s ADS1115.
• ADS1115 is a 16-bit IIC-compatible chip.High-precision and low-power analog-to-digital converter, at the same time, a digital comparator is built into the ADS1115 for undervoltage andOvervoltage detection.
• The power supply range of the module is 2V~5.5V, and 6 input ranges can be set, ±0.256V、 ±0.512V, ±1.024V, ±2.048V, ±4.095V and ±6.144V, the fastest sampling rateIt is 860SPS.
• The ADS1115 has an input multiplexer (MUX), which can achieve two-channel differenceDynamic input measurement or four-channel single-ended input measurement.
• The module can be widely used in portable instruments and electricityIn scenarios such as battery voltage and current health, temperature measurement system.
