Introducing the ADS114S08IPBSR from Texas Instruments

The ADS114S08IPBSR is a precision, 16-bit analog-to-digital converter (ADC) from Texas Instruments, designed to meet the exacting requirements of temperature and pressure sensing, as well as other industrial measurement applications. This versatile component is an integral part of the ADS114S08 family, renowned for its exceptional performance in monitoring physical processes where accuracy and reliability are paramount.

At the heart of the ADS114S08IPBSR lies a delta-sigma ADC with a fully differential input, providing a high level of noise rejection and ensuring the integrity of the signal conversion process. It features an internal oscillator, temperature sensor, and burnout current sources, which contribute to its self-contained functionality and ease of integration into various systems.

The device boasts an impressive array of built-in features, including a low-drift voltage reference, an oscillator, and a temperature sensor that together facilitate a simplified design process, reducing the need for external components. This integration not only saves space on the PCB but also enhances the overall system reliability due to fewer discrete parts.

The ADS114S08IPBSR is equipped with a flexible input multiplexer (MUX) that supports eight single-ended inputs or four differential inputs, allowing it to cater to a wide range of sensor types and configurations. This flexibility is further enhanced by the programmable gain amplifier (PGA), which offers gains from 1 to 128, thus accommodating signals of various amplitudes for precise measurement.

Communication with microprocessors is seamless, thanks to the SPI-compatible serial interface. The device also includes a data output rate (DOR) that is selectable from 5 to 2k samples per second (SPS), providing designers with the ability to optimize speed and resolution for their specific application needs.

Encased in a compact QFN-32 package, the ADS114S08IPBSR operates over a wide supply range of 2.7V to 5.5V, making it suitable for both portable and line-powered applications. Its extended industrial temperature range of -40°C to +125°C ensures reliable performance across diverse environmental conditions.

With its precision, integrated features, and robust design, the ADS114S08IPBSR from Texas Instruments stands out as a superior choice for engineers and designers looking for a high-quality ADC solution for their measurement and control systems.
