High-Precision 16-Bit Analog-to-Digital Converter with Integrated Temperature Sensor and SPI Interface for Sensor Measurement Systems

The ADS1118IDGSR is a high-accuracy 16-bit analog-to-digital converter designed for precise measurement of analog signals in embedded and industrial electronics. Developed by Texas Instruments, this device integrates a delta-sigma ADC, programmable gain amplifier (PGA), internal temperature sensor, voltage reference, and oscillator into a compact solution. The SPI-compatible interface allows seamless communication with microcontrollers, simplifying integration into data acquisition systems.

This ADC supports up to four single-ended inputs or two differential inputs, enabling flexible sensor interfacing in applications such as industrial monitoring, temperature sensing, battery-powered instrumentation, and portable measurement devices. With its low power consumption and compact VSSOP-10 package, the ADS1118 is well suited for space-constrained designs while delivering reliable high-resolution measurements for modern embedded systems.
