ADS8558IPM

Analog To Digital Converters (ADC) Overview

The ADS8558IPM is a six-channel, simultaneous sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 12-bit resolution and operates at a sampling rate of 730 kSPS. The device utilizes a successive approximation register (SAR) architecture and accepts single-ended inputs. It supports both parallel and serial interfaces for data output. Power requirements include an analog supply voltage range of 4.5 V to 5.5 V and a digital supply voltage range of 2.7 V to 5.5 V. The component is housed in a 64-pin LQFP package and offers a signal-to-noise ratio of 73.9 dB with differential nonlinearity of +/- 0.5 LSB and integral nonlinearity of +/- 0.75 LSB.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling across all six channels ensures precise phase alignment between input signals without inter-channel delay.
• Integrated internal oscillator eliminates the need for external clock sources, simplifying system design and reducing component count.
• Daisy-chainable architecture allows multiple devices to be connected sequentially, facilitating scalable multi-channel data acquisition systems.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-speed multi-channel data acquisition
• Medical imaging equipment such as ultrasound and CT scanners needing synchronized channel sampling
• Structural health monitoring and vibration analysis in aerospace and defense applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature grade. Ensure compatibility with existing board layouts regarding the LQFP-64 footprint. Confirm power supply rails match the specified analog and digital voltage ranges before integration. Check for moisture sensitivity level requirements during storage and handling procedures.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of six channels is critical for maintaining signal integrity. Consider the 12-bit resolution and 730 kSPS speed against application bandwidth requirements. Evaluate the SAR architecture's power consumption versus other ADC types. Verify interface compatibility with the host microcontroller or DSP for both parallel and serial modes.

Analog To Digital Converters (ADC) Part Context

The ADS8558IPM belongs to the ADS855x family of simultaneous sampling ADCs from Texas Instruments. This series includes variants with different resolutions and channel counts, such as the ADS8555 and ADS8528. The IPM suffix denotes the specific LQFP-64 package variant designed for surface-mount assembly in industrial environments.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS8558IPMR for reel packaging. For higher resolution needs, consider the ADS8555. For increased channel counts, evaluate the ADS8528. Ensure pinout and electrical specifications remain compatible before swapping components.
