HI7190IBZ

Analog To Digital Converters (ADC) Overview

The HI7190IBZ is a high-precision, 24-bit Sigma-Delta Analog-to-Digital Converter (ADC) manufactured by Renesas Electronics Corporation. It features a single analog input channel and operates within an extended industrial temperature range of -40°C to +85°C. The device supports dual power supplies with maximum ratings of ±5 V for the analog section. It is available in PDIP-20 and SOIC-20 surface-mount packages, ensuring compatibility with standard PCB layouts for precision measurement applications requiring high resolution and low noise performance.

Analog To Digital Converters (ADC) Feature Summary

• Delivers 24-bit resolution using Sigma-Delta modulation architecture for high accuracy
• Supports bipolar analog input signals with specified supply voltage ranges
• Operates reliably across the full industrial temperature spectrum

Analog To Digital Converters (ADC) Applications

• Precision weighing scales and load cell interfaces
• Industrial process control sensor signal conditioning
• High-resolution data acquisition systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific package variant (PDIP or SOIC) required for your design, as both are documented for this part number. Confirm that the ±5 V supply rails match your system's power architecture. Ensure thermal management aligns with the -40°C to +85°C operating range specifications provided in the official datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 24-bit resolution and low noise are critical for measuring small differential signals from sensors. The Sigma-Delta topology is suitable for low-frequency, high-accuracy applications. Compare against other Renesas ADCs if higher sampling rates or different interface protocols are needed.

Analog To Digital Converters (ADC) Part Context

This device belongs to Renesas' portfolio of precision analog-to-digital converters, historically associated with the Intersil brand acquired by Renesas. It serves as a specialized solution for applications demanding high linearity and stability, distinct from general-purpose microcontroller-integrated ADCs.

Analog To Digital Converters (ADC) Replacement Considerations

Check for updated revisions within the HI7190 family. Verify pinout compatibility if considering alternative 24-bit Sigma-Delta ADCs from other manufacturers, as interface and supply requirements may differ.
