ADS114S08IPBS

Analog To Digital Converters (ADC) Overview

The ADS114S08IPBS is a 16-bit delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 32-pin TQFP package and supports an SPI digital interface. The device operates with an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 2.7 V to 3.6 V. It provides 12 input channels with a maximum sampling rate of 4 kSPS. The architecture includes a programmable gain amplifier (PGA), internal temperature sensor, and GPIOs.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a low-noise programmable gain amplifier with gain settings from 1 to 128 for signal conditioning.
• Includes dual matched programmable excitation current sources for RTD biasing applications.
• Features a built-in 2.5 V reference voltage source with low drift characteristics.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel sensor data acquisition.
• Temperature measurement using resistance temperature detectors (RTDs).
• Strain gauge and load cell monitoring in weighing scales.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against official documentation to confirm package type and commercial grade specifications. Ensure compatibility with existing PCB footprints for the 32-TQFP form factor. Confirm that the analog and digital power supply rails match the required operating ranges before integration into the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-resolution multi-channel acquisition is required without external amplifiers. Compare channel count requirements against the ADS114S06 variant if fewer inputs are sufficient. Evaluate the trade-off between the integrated PGA noise performance and the system's overall dynamic range needs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS114S0x family of precision ADCs designed for low-power industrial applications. It shares functional similarities with the ADS114S06 but offers double the number of analog input channels. The IPBS suffix indicates a specific commercial-grade version in a TQFP-32 package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS114S08BIPBS is a verified alternative offering extended industrial temperature range capabilities while maintaining pin compatibility. Verify that the thermal management requirements align with the specific operating environment constraints.
