RS8524XQ

Overview

The RS8524XQ is a quad zero-drift CMOS operational amplifier manufactured by Runic Technology. It features an input offset voltage of ±1 µV (typical) and an input offset drift of ±0.005 µV/°C. The device operates on a supply voltage range of +2.3 V to +5.5 V with a quiescent current of 60 µA per amplifier. Key electrical parameters include a gain-bandwidth product of 350 kHz, a slew rate of 0.17 V/µs, and a typical noise density of 3.2 µVp-p from 0.01 Hz to 10 Hz. It provides rail-to-rail input and output capabilities within a 14-TSSOP package.

Feature Summary

• Utilizes auto-zero techniques to achieve near-zero offset voltage drift over time and temperature variations.
• Provides rail-to-rail input and output swing capability for maximum dynamic range in low-voltage applications.
• Delivers high precision performance with ultralow noise and power consumption characteristics.

Applications

• Temperature Sensors
• Medical and Industrial Instrumentation
• Pressure Sensors
• Battery-Powered Instrumentation
• Active Filtering

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape-and-reel quantity specifications. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the datasheet revision history to validate the most current electrical characteristics and pin configuration details before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high precision with minimal offset drift over extended temperature ranges. The quad configuration allows multiple channels in a single package, reducing board space compared to individual amplifiers. Ensure the application supply voltage remains within the specified 2.3 V to 5.5 V range to maintain optimal performance and prevent damage.

Part Context

The RS8524XQ belongs to the RS852 series of zero-drift operational amplifiers, which includes single (RS8521), dual (RS8522), and quad (RS8524) variants. This family shares common core technologies such as auto-zeroing and CMOS architecture. The RS8524 specifically integrates four independent amplifiers into a 14-lead TSSOP or SOIC package, offering a compact solution for multi-channel signal conditioning tasks.

Replacement Considerations

Direct substitutes within the same family include RS8521XF, RS8521XK, RS8521XM, RS8522XK, RS8522XM, and RS8524XP. Verify pin compatibility and package dimensions when replacing the RS8524XQ with other members of the RS852 series to ensure proper integration into existing designs.
