Description and Introduction

24-Bit, High Precision, Sigma Delta A/D Converter The HI7191IBZ is a precision analog-to-digital converter (ADC) manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications:  

- **Resolution**: 24-bit  
- **Interface Type**: Serial (SPI-compatible)  
- **Input Type**: Differential  
- **Sampling Rate**: Up to 15.6 Hz (varies with filter settings)  
- **Input Voltage Range**: ±2.5V (bipolar)  
- **Power Supply**: Single +5V  
- **Operating Temperature Range**: -40°C to +85°C  
- **Package**: 28-lead SOIC  
- **Features**: On-chip calibration, low noise, programmable gain (1x to 128x)  
- **Applications**: Weigh scales, industrial process control, medical instrumentation  

This ADC is designed for high-precision measurement applications.  

(Note: Since Intersil was acquired by Renesas, verify availability with Renesas or authorized distributors.)

Application Scenarios & Design Considerations

24-Bit, High Precision, Sigma Delta A/D Converter

Alternative Part Number

  • AD7190BRUZ --: Pin-compatible 24-bit sigma-delta ADC with similar functionality and performance, from the same product family lineage after Intersil/Renesas and ADI portfolio overlap.
  • ADS1256IDBR --: 24-bit low-noise sigma-delta ADC offering comparable resolution and interface, suitable as a functional replacement in precision measurement designs.
  • MCP3421A0T-E/CH --: 18-bit delta-sigma ADC with I2C interface, a viable lower-resolution alternative for applications where exact 24-bit precision is not critical.
