No doubt, there are inner ADCs that are perfect for analog inputs for Arduino. Interfacing the ADS1115 to an Arduino isn’t rocket science because it’s an outer digital-analog converter (ADC). Pin Configuration of The ADS1115 How to interface ADS1115 16-bit ADC with ArduinoĮngineering student interfacing ADS1115 to Arduino The operating temperature ranges from -40 0C to +125 0C.īut that’s not all.The conversion rate ranges from 8 to 860Bps.Digital acquisition output range from 0 to 32767 for positive and 32768 to 65535 for negative.ADS1115’s reference input offers negative and positive pressure.The device initializes when the power comes up.

Continuous and single conversion operation mode.An ultra-small package with a dimension of 2 x 1.5 x 0.4 mm.It also works in one trigger mode that powers off automatically after a complete conversion. As a result, the PSV measures large and small high-resolution signals.įurther, the AD1115 features an input MUX (multiplexer) with four single-ended or two differential inputs.

The onboard PGA offers a range input of ☒56mV from the PSV (power supply voltage).

Also, the device comes with an onboard PGA (programmable gain amplifier). The ADS 115 executes a conversion rate of about 860 SPS (samples per second). Also, it utilizes one working power that ranges from 2.0 volts to 5.5 volts. While at it, the device selects four IC2 slave addresses. So, it transfers data via a compatible serial interface (I2C). Typically, this module features an oscillator and onboard reference. So, you can use these modules to strengthen, increase accuracy, and perform data analysis by converting analog to digital. In other words, the device is an analog to digital converter that has a reference voltage internally. The ADS115 ADC module is a small device with low power and a 16-bit precision AD converter. You’ll learn more about what it is, the pin configuration, working principle, how to interface it, and more. This article will give you a great head start if you’re new to this low-power device. Are you working with automotive electronics, high-precision instrumentation, or other high-precision collections? Or do you need a reliable device that can change analog to digital for data analysis, amplify, and enhance accuracy? Then, what you need is the ADS1115.
