ADS114S08BIRHBT

Analog To Digital Converters (ADC) Overview

The ADS114S08BIRHBT is a 16-bit, 4kSPS delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single converter with 12 input channels supporting differential, pseudo-differential, and single-ended configurations. The device operates on an analog supply voltage ranging from 2.7 V to 5.25 V and a digital supply voltage between 2.7 V and 3.6 V. It utilizes an SPI interface for communication and includes internal and external reference options. Key specifications include a 32-VQFN package, operation temperatures from -40°C to +125°C, and integrated features such as programmable gain amplifiers (PGA), excitation current sources (iDACs), GPIO, and a temperature sensor.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 12-channel multiplexer with programmable gain amplifier for flexible signal conditioning
• Built-in excitation current sources suitable for driving resistive sensors like RTDs
• On-chip oscillator and temperature sensor reduce external component count
• Supports both internal and external voltage reference configurations

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel precision measurement
• Weight scales and load cell instrumentation
• RTD and thermocouple temperature monitoring applications
• Medical equipment requiring high-resolution analog signal acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRHBT indicates the VQFN-32 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the ordering part number matches the exact pinout and thermal pad specifications required by the design. Cross-reference with the manufacturer's latest datasheet to confirm active status and any potential PCN changes affecting material composition or manufacturing location.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 12 input channels are required within a compact footprint. The 16-bit resolution and 4kSPS data rate suit applications needing moderate speed with high accuracy. Consider the VQFN-32 package for surface-mount designs where board space is limited. Verify that the system power budget accommodates the specified analog and digital supply ranges. Evaluate if the integrated iDACs meet the excitation current requirements for the connected sensors.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS114S0x family of precision delta-sigma ADCs. It shares architectural similarities with the ADS114S06B but offers increased channel count. The device is designed for high-performance industrial applications. It complements other Texas Instruments data conversion products by providing integrated signal chain components including PGA and reference management in a single IC.

Analog To Digital Converters (ADC) Replacement Considerations

ADS114S08BIPBSR offers identical electrical performance in a TQFP-32 package. ADS114S06B provides similar functionality with fewer input channels. Verify pin compatibility and thermal characteristics when substituting packages. Ensure software register configurations remain compatible across the family variants.
