Description

Product Describtion

The ADS1118 is a precision, low power, 16-bit analog-to-digital converter (ADC) that provides all features necessary to measure the most common sensor signals in an ultra-small, leadless X2QFN-10 package or a VSSOP-10 package. The ADS1118 integrates a programmable gain amplifier (PGA), voltage reference, oscillator and high-accuracy temperature sensor. These features, along with a wide power supply range from 2 V to 5.5 V, make the ADS1118 ideally suited for power- and space-constrained, sensor-measurement applications.

The ADS1118 can perform conversions at data rates up to 860 samples per second (SPS). The PGA offers input ranges from ±256 mV to ±6.144 V, allowing both large and small signals to be measured with high resolution. An input multiplexer (MUX) allows to

measure two differential or four single-ended inputs.The high-accuracy temperature sensor can be used for system-level temperature monitoring or cold- junction compensation for thermocouples.

The ADS1118 operates either in continuous- conversion mode, or in a single-shot mode that automatically powers down after a conversion. Single-shot mode significantly reduces current consumption during idle periods. Data are transferred through a serial peripheral interface (SPI™). The ADS1118 is specified from –40°C to +125°C.

ADS1118 16-bit ADC module with an Arduino.
An analog-to-digital converter (ADC) is a device that converts an analog signal, such as the voltage output of a sensor, into a digital representation that a microcontroller can understand and process.
An ADC can be used to read and process analog signals on the Arduino, which is a microcontroller.

There are several ADCs available for use with the Arduino, ranging from simple, low-resolution converters to high-precision, high-resolution devices. For this project, we are using ADS1118 16-Bit ADC.

There are just a few basic steps, and no additional hardware is needed for the interface. As a result, the code is simpler to comprehend. Let’s dive in right now and find out more!
