ADS114S08BIPBS

Analog To Digital Converters (ADC) Overview

The ADS114S08BIPBS is a 16-bit, 12-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single sigma-delta architecture with an integrated programmable gain amplifier (PGA) and multiplexer. The device supports differential, pseudo-differential, and single-ended input types via an SPI interface. It operates on an analog supply voltage ranging from 2.7 V to 5.25 V and a digital supply voltage of 2.7 V to 3.6 V. The maximum sampling rate is 4 kSPS. It is housed in a 32-TQFP package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated excitation current sources (iDACs) for sensor biasing
• Built-in 50 Hz and 60 Hz line frequency rejection capabilities
• On-chip temperature sensor and general-purpose I/O pins

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPBS against the official datasheet to confirm the TQFP-32 package variant. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Confirm that the external power supplies match the specified analog and digital voltage limits before integration into the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high channel count is required alongside 16-bit resolution. The internal PGA reduces the need for external amplification. Consider the 32-TQFP package constraints for PCB layout. Verify that the SPI interface timing meets the system clock requirements for the desired 4 kSPS throughput.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS114S08B family of precision ADCs. It shares core architectural features with other members but is distinguished by its specific pinout and packaging configuration. The B-series designation typically indicates specific performance grades or manufacturing revisions within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS114S08BIPBSR is a reel-based version of the same functional device. Other variants like the ADS114S08IPBSR offer extended industrial temperature ranges. Verify pin compatibility and electrical specifications before substituting.
