ADA4898-1YRDZ-R7

Overview

The ADA4898-1YRDZ-R7 is a single-channel, high-speed voltage feedback operational amplifier manufactured by Analog Devices Inc. It features ultralow noise of 0.9 nV/√Hz and ultralow distortion of −93 dBc at 500 kHz. The device operates with supply voltages ranging from ±5 V to ±16 V and maintains unity-gain stability. Key electrical parameters include a 65 MHz bandwidth, 55 V/µs slew rate, and 8 mA quiescent current per amplifier. It includes a power-down pin for the single package and is housed in an 8-lead SOIC_N_EP (RD-8-4) package.

Feature Summary

• Ultralow noise and distortion performance suitable for precision signal processing
• Unity-gain stable architecture with wide supply voltage flexibility
• Integrated power-down feature for reduced standby power consumption
• Exposed paddle thermal pad design for improved heat dissipation

Applications

• Instrumentation systems
• Active filters
• DAC buffers
• SAR ADC drivers
• Optoelectronics

Procurement Notes

Verify the specific ordering suffix R7 indicates reel packaging when sourcing. Confirm the RD-8-4 package designation matches the required footprint. Ensure the single-channel configuration aligns with system requirements rather than the dual-channel variant. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this component for applications requiring high speed combined with low noise and distortion. It is suitable for 16-bit and 18-bit systems operating within the specified supply range. Consider the exposed paddle requirement for proper PCB layout and thermal management. Evaluate the power-down functionality if energy efficiency during idle periods is a critical design constraint.

Part Context

This part belongs to the ADA4898 family of high-voltage, low-noise op amps. It shares core specifications with the dual-channel ADA4898-2 but provides a single amplifier in an 8-lead SOIC package. The family utilizes proprietary bipolar processing technology to achieve high linearity and fast transient response while maintaining precision DC characteristics across the industrial temperature range.
