ADS114S08IPBSR

Analog To Digital Converters (ADC) Overview

The ADS114S08IPBSR 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 voltage. The device supports data rates up to 4 kSPS and utilizes a serial peripheral interface (SPI) for communication. It operates with analog supply voltages ranging from 2.7 V to 5.25 V and digital supply voltages from 2.7 V to 3.6 V. The component is housed in a 32-pin TQFP package measuring 5 mm x 5 mm. It functions within an industrial temperature range of -50°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-channel multiplexer with a programmable gain amplifier for flexible signal conditioning.
• Includes an internal precision reference voltage source to reduce external component requirements.
• Features excitation current sources suitable for driving resistive sensors such as RTDs.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel sensor acquisition.
• High-precision weighing scales utilizing load cells or strain gauges.
• Thermocouple and resistance temperature detector (RTD) measurement modules.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPBSR to confirm the industrial temperature grade (-50°C to +125°C) and TQFP-32 packaging. Ensure compatibility with system power rails, specifically the separate analog and digital supply requirements. Confirm that the target application does not require the extended performance specifications found in the B-grade variants of this family.

Analog To Digital Converters (ADC) Selection Notes

Select this model when twelve differential or single-ended channels are required within a single ADC unit. The IPBSR variant is appropriate for harsh industrial environments due to its wider operating temperature range compared to commercial grades. Consider the B-version if tighter gain error specifications or lower noise performance are critical for the design.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS114S0x family of high-performance sigma-delta ADCs. It shares architectural similarities with the ADS114S06 but provides additional input channels. The IPBSR designation indicates the standard industrial temperature rating and surface-mount TQFP packaging format used by Texas Instruments for this series.

Analog To Digital Converters (ADC) Replacement Considerations

ADS114S08BIPBSR offers improved electrical specifications including lower noise and tighter gain error while maintaining identical pinout and functionality. ADS114S08EVM serves as a development tool rather than a direct functional replacement.
