Overview
The ADS8584SIPMR is a 16-bit, 4-channel successive approximation register (SAR) analog-to-digital converter (ADC) designed for high-precision data acquisition systems.
It is widely used in industrial automation, data acquisition modules, and motor control systems, where high accuracy, wide input voltage range, and reliable sampling performance are required.
This device integrates analog front-end circuitry and supports bipolar inputs, simplifying system design while maintaining excellent conversion performance.
Core Parameters

Performance Comparison
| Feature | ADS8584SIPMR | Typical 12-bit ADC | Delta-Sigma ADC |
|---|---|---|---|
| Resolution | 16-bit | 12-bit | 16–24 bit |
| Sampling Speed | High (200 kSPS) | Medium | Low |
| Latency | Very Low | Low | High |
| Input Voltage Range | Wide (±10 V) | Limited | Limited |
| System Complexity | Low | Low | High |
Compared with lower-resolution ADCs, the ADS8584SIPMR provides superior accuracy and signal fidelity, while offering much lower latency and higher throughput than delta-sigma ADC solutions.
