ADS8586SIPMR

Analog To Digital Converters (ADC) Overview

The ADS8586SIPMR is a 16-bit, 6-channel simultaneous-sampling analog-to-digital converter (ADC) from Texas Instruments. It utilizes a successive approximation register (SAR) architecture with a maximum sampling rate of 250 kSPS per channel. The device integrates a complete analog front end, including programmable gain amplifiers (PGA) with 1 MΩ input impedance, low-pass filters, and over-voltage protection. It operates on a 4.75 V to 5.25 V analog supply and a 2.3 V to 5.25 V digital supply. Key performance metrics include a signal-to-noise ratio (SNR) of 96.4 dB, differential nonlinearity (DNL) of ±0.35 LSB, and integral nonlinearity (INL) of ±0.45 LSB. It supports serial, parallel, and byte-parallel interfaces and functions within a temperature range of -40°C to +125°C in a 64-pin LQFP package.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling across six channels ensures precise phase alignment for multi-phase power monitoring applications.
• Integrated analog front end includes high-impedance programmable gain amplifiers and input clamping protection, eliminating the need for external driver circuits.
• Flexible digital interface supports serial, parallel, and byte-parallel communication modes for compatibility with various host controllers.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-speed multi-channel data acquisition
• Power quality monitoring and grid instrumentation
• Medical imaging equipment such as ultrasound and CT scanners

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IPMR' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the required operating voltage ranges align with the system's analog and digital power supplies. Ensure ESD handling procedures are followed due to the sensitivity of the CMOS inputs. Check for moisture sensitivity level requirements during storage and reflow soldering processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when six synchronized channels are required at speeds up to 250 kSPS. Compare against the ADS8584S for fewer channels or higher speed, and the ADS8588S for eight channels at lower throughput. Ensure the single-ended input configuration matches the sensor interface. Verify that the integrated 2.5 V reference meets accuracy requirements or consider external references if stricter precision is needed.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS85xxS family of synchronous sampling ADCs designed for industrial and medical applications. It shares architectural similarities with the ADS8584S and ADS8588S but offers a specific balance of six channels and 250 kSPS throughput. The IPMR suffix indicates the reel-packaged version suitable for automated surface-mount assembly lines.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8586SIPM is the tray-packaged equivalent of the same functional device. ADS8584SIPMR offers four channels at 330 kSPS. ADS8588SIPMR provides eight channels at 200 kSPS. Direct pin-compatible substitutes within the same series maintain similar analog front-end characteristics.
