SGM8054XTS14/TR Rail-to-Rail Output CMOS Operational Amplifiers

Technical Comparison: SGMICRO SGM8054XTS14/TR vs. Analog Devices AD8054ARUZ / AD8054ARUZ-REEL7

1. Power Efficiency and Low Quiescent Current
The SGM8054XTS14/TR features an exceptionally low quiescent current of 1.2mA per channel (typical), compared to the 5mA per channel in AD8054ARUZ and AD8054ARUZ-REEL7. This significant power saving—over 75% reduction—translates to lower overall system power consumption, reduced thermal stress, and longer battery runtime, especially in portable or thermally sensitive designs.

2. Supply Voltage Range and System Flexibility
SGM8054XTS14/TR operates over a wide supply voltage range of 2.5V to 5.5V, providing excellent compatibility with both low-voltage digital systems and traditional analog rails. In contrast, AD8054ARUZ series supports 3V to 6V operation, making it less ideal for ultra-low-voltage or single-cell lithium battery systems. This wider range makes SGM8054XTS14/TR better suited for modern, low-voltage mixed-signal platforms.

3. High-Speed Performance and Slew Rate
Despite its low-power nature, the SGM8054XTS14/TR maintains high-speed signal processing capabilities, featuring a 300MHz gain-bandwidth product and an ultra-fast 1400V/μs slew rate, which matches the performance of AD8054ARUZ and AD8054ARUZ-REEL7. These characteristics enable both devices to support video, RF, and high-speed signal conditioning applications. However, SGM8054XTS14/TR achieves this at dramatically lower power.

4. Output Swing and Rail-to-Rail Capability
SGM8054XTS14/TR offers rail-to-rail output, maximizing dynamic range and simplifying signal chain design in single-supply systems. In comparison, the AD8054ARUZ series provides a limited output swing, which can restrict headroom in low-voltage applications. This gives the SGMICRO part a clear advantage in maximizing signal integrity without needing additional signal buffering or level shifting.

5. Package Type and Integration Efficiency
Both SGM8054XTS14/TR and AD8054ARUZ are available in 14-pin TSSOP packages, offering pin-to-pin compatibility. However, the lower power dissipation of SGM8054XTS14/TR leads to improved thermal performance and reduced need for heat mitigation, making it more suitable for compact or high-channel-density systems.

6. Temperature Range and Reliability
The SGM8054XTS14/TR operates reliably across a -40°C to +125°C temperature range, equivalent to or better than AD8054ARUZ and AD8054ARUZ-REEL7. This makes it ideal for industrial and automotive environments requiring robustness under wide environmental conditions.

7. Availability, Cost, and Supply Chain Advantage
SGMICRO offers cost-effective pricing, shorter lead times, and strong local technical support, while AD8054ARUZ series may face higher BOM cost and global supply limitations. For OEMs and design engineers concerned with procurement flexibility and long-term product lifecycle support, the SGM8054XTS14/TR presents a more sustainable and economical choice.

Conclusion
The SGM8054XTS14/TR from SGMICRO delivers equivalent high-speed performance to the AD8054ARUZ/REEL7 series but with significantly lower power consumption, wider voltage operation, rail-to-rail output, and strong thermal efficiency. These features, combined with its robust temperature range and reliable sourcing, make it a compelling alternative for high-speed, low-power analog signal applications.
