ADS8548SRGCT

Analog To Digital Converters (ADC) Overview

The ADS8548SRGCT is a high-performance analog-to-digital converter manufactured by Texas Instruments. It features an 8-channel simultaneous-sampling architecture with 14-bit resolution, utilizing a Successive Approximation Register (SAR) structure. The device supports sampling rates up to 600 kS/s per channel and accepts single-ended bipolar input signals within a ±12 V range. It operates on a 4.5 V to 5.5 V analog supply and a 2.7 V to 5.5 V digital supply. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 85 dB and a SINAD of 84 dB. The component is housed in a 64-pin VQFN package and supports both parallel and serial interfaces.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling across all eight channels ensures precise phase alignment for multi-axis applications.
• Integrated internal oscillator eliminates the need for external clocking circuitry.
• Daisy-chainable output interface simplifies data retrieval from multiple cascaded devices.

Analog To Digital Converters (ADC) Applications

• Multi-axis motor control systems requiring synchronized current sensing
• Industrial process monitoring with multiple isolated sensor inputs
• High-density data acquisition systems for factory automation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGCT' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the ordering part number matches the exact pinout and temperature rating required for the target design environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of eight single-ended signals is required at 14-bit resolution. Verify compatibility with the system's voltage domains, as the analog and digital supplies have distinct operating ranges. Confirm that the VQFN package size fits the available PCB real estate constraints.

Analog To Digital Converters (ADC) Part Context

This model belongs to the ADS8548 family of simultaneous-sampling ADCs. It shares core architectural similarities with other members like the ADS8548SPM but differs in package type and shipping format. The family is designed for applications demanding high channel count and synchronization without sacrificing resolution.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same series include the ADS8548SPM. Verify pin compatibility and thermal performance differences between the LQFP and VQFN packages before swapping components in an existing layout.
