ADS114S08BIRHBR

Analog To Digital Converters (ADC) Overview

The ADS114S08BIRHBR is a 16-bit, 12-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a sigma-delta architecture with an SPI interface and supports differential or single-ended inputs. The device operates within 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 a sampling rate of 4 kSPS and includes programmable gain amplifiers (PGA), excitation current sources (iDACs), GPIO, an oscillator, and a temperature sensor. The component is housed in a 32-pin VQFN package and functions reliably across a temperature range of -40°C to +125°C.

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 resistive sensor applications such as RTDs
• On-chip oscillator and temperature sensor reduce external component count

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel precision measurement
• Weight scales and load cell interfaces utilizing bridge sensors
• Thermocouple and RTD temperature monitoring networks

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRHBR corresponds to the VQFN-32 package and reel packaging configuration required for your assembly line. Confirm that the analog and digital power supply rails match the specified voltage ranges before integration. Ensure ESD handling procedures are followed due to the sensitivity of the input stages and the moisture sensitivity level indicated in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this model when twelve independent channels are necessary within a compact footprint. The ADS114S08BIRHBR is appropriate for designs needing integrated current sources for bridge excitation without external circuitry. Compare channel count against the ADS114S06B series if fewer inputs suffice, or consider alternative packages like TQFP if board space allows for larger footprints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS114S0x family of high-precision delta-sigma ADCs from Texas Instruments. It shares architectural similarities with the ADS114S06B but offers double the channel count. The part is designed for applications demanding high accuracy and low noise in industrial environments, serving as a direct replacement for older generation multi-channel ADCs in modern sensor interfaces.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS114S08BIPBSR serves as a pin-compatible alternative in a TQFP-32 package. Verify that the thermal characteristics and pinout alignment meet the PCB layout requirements before substituting.
