ADS8548SRGCR

Analog To Digital Converters (ADC) Overview

The ADS8548SRGCR is a 14-bit, 8-channel simultaneous-sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with a maximum sampling rate of 600 kSPS per channel. The device supports bipolar input ranges up to ±12 V and operates with an analog supply voltage between 4.5 V and 5.5 V, alongside a digital supply range of 2.7 V to 5.5 V. Key performance metrics include a typical signal-to-noise ratio (SNR) of 85 dB and a SINAD of 84 dB. It integrates an internal oscillator and reference, offers daisy-chainable connectivity via SPI or parallel interfaces, and functions within an industrial temperature range of -40°C to +125°C in a 64-pin VQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling across eight independent channels ensures precise phase alignment for multi-phase motor control and power conversion applications.
• Integrated high-speed SAR architecture eliminates the need for external clock sources by utilizing an internal oscillator.
• Wide bipolar input capability accommodates direct sensing of high-voltage signals without requiring external attenuation circuitry.

Analog To Digital Converters (ADC) Applications

• Multi-axis servo drives and motor control systems
• Industrial process automation and data acquisition
• Power quality monitoring and grid instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SRGCR' against the manufacturer's official datasheet to confirm the package type, tape-and-reel quantity, and environmental compliance status. Ensure that the ordering information matches the exact pinout and electrical specifications required for the target design, as suffix variations may indicate differences in packaging or testing criteria.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel acquisition is critical for maintaining signal integrity in dynamic systems. The 14-bit resolution balances precision with speed, making it suitable for applications where 600 kSPS throughput is sufficient. Consider the ±12 V input range if interfacing directly with sensors, avoiding additional signal conditioning stages compared to lower-voltage ADCs.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS854x family of high-speed, multi-channel ADCs designed for demanding industrial environments. It complements other Texas Instruments data converters by offering simultaneous sampling capabilities, which are distinct from sequential sampling architectures found in general-purpose ADCs. The part is engineered for robustness in electrically noisy settings common in factory automation.
