ADS114S08IRHBR

Analog To Digital Converters (ADC) Overview

The ADS114S08IRHBR is a 16-bit, 12-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an integrated multiplexer, programmable gain amplifier (PGA), and internal reference. The device supports differential, pseudo-differential, and single-ended input types with a maximum sampling rate of 4 kSPS. It operates on analog supply voltages ranging from ±2.5 V to 2.7 V–5.25 V and digital supplies from 2.7 V to 3.6 V. Communication is handled via a standard SPI interface. The component is housed in a 32-VQFN package measuring 5x5 mm and is rated for industrial temperatures between -50°C and +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated signal chain comprising a 12-channel multiplexer, programmable gain amplifier, and delta-sigma modulator.
• Supports multiple input configurations including differential, pseudo-differential, and single-ended connections.
• Includes built-in excitation current sources (iDACs) for sensor biasing and temperature sensing capabilities.

Analog To Digital Converters (ADC) Applications

• Precision industrial process control systems requiring multi-channel sensor acquisition.
• Strain gauge and load cell measurement applications utilizing bridge sensors.
• Thermocouple and RTD temperature monitoring in harsh industrial environments.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRHBR confirms the 32-VQFN(5x5) package and extended temperature range. Confirm RoHS compliance status matches project requirements. Check moisture sensitivity level (MSL 3) handling constraints during assembly. Ensure voltage supply rails align with the specified analog and digital ranges before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 12 channels are required within a compact footprint. Compare against ADS114S06 if fewer channels suffice. Consider ADS114S08B variants if automotive qualification is needed. Verify that the 4 kSPS maximum data rate meets system throughput needs. Ensure SPI compatibility with the host microcontroller.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS114S08 family of precision ADCs. It shares architectural similarities with the ADS114S06 but offers double the channel count. It complements other Texas Instruments data converters like the ADS1204 series but focuses on lower speed, higher channel density applications. The IRHBR suffix denotes the specific tape-and-reel packaging variant.

Analog To Digital Converters (ADC) Replacement Considerations

ADS114S08IRHBT is the tray-packaged equivalent of the same functional device. ADS114S06BIRHBR offers similar features but with only 6 channels. Direct pin-for-pin replacements within the same package require verifying channel count and temperature range specifications.
