ADS114S08IRHBT

Analog To Digital Converters (ADC) Overview

The ADS114S08IRHBT is a 16-bit, 12-channel delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It features a single sigma-delta modulator with a multiplexer and programmable gain amplifier (PGA). The device supports differential, pseudo-differential, and single-ended inputs with an SPI interface. It operates on analog supply voltages from 2.7 V to 5.25 V and digital supply voltages from 2.7 V to 3.6 V. The maximum sampling rate is 4 kSPS. It includes internal and external reference options, excitation current sources, GPIOs, and a temperature sensor. The component is housed in a 32-pin VQFN package and functions within 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 input configurations
• Built-in excitation current sources suitable for bridge sensor applications
• On-chip oscillator and temperature sensor for system monitoring
• Supports both internal and external voltage reference connections

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Weigh scales and load cell measurement platforms
• Thermocouple and RTD temperature measurement instrumentation
• Strain gauge and pressure sensor data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRHBT indicates the VQFN-32 package and industrial temperature grade during sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure moisture sensitivity level handling procedures are followed upon receipt to prevent damage during surface mount assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this model when twelve independent channels are required within a single integrated circuit. The 16-bit resolution and 4 kSPS speed suit precision low-frequency measurements. Consider the integrated PGA and excitation drivers to reduce external component count compared to discrete solutions. Verify that the VQFN-32 footprint aligns with the target PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS114S0x family of high-performance delta-sigma ADCs. It shares architectural similarities with the ADS124S08 but offers lower 16-bit resolution compared to the 24-bit variants. The device complements other Texas Instruments data converters by providing a balance of channel count and precision for cost-sensitive industrial applications.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS114S08IPBSG4 is a tray-packaged alternative within the same series. The ADS114S06BIRHBT serves as a pin-compatible option with six channels instead of twelve. Cross-reference datasheets to confirm functional equivalence before substitution.
