ADA4898-2YRDZ-R7

Overview

The ADA4898-2YRDZ-R7 is a dual-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 a wide supply voltage range 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 is housed in an 8-lead SOIC_N_EP package.

Feature Summary

• Ultralow noise and distortion performance suitable for precision signal processing
• Unity-gain stable architecture with high slew rates
• Wide supply voltage operation supporting various system requirements
• Integrated cancellation circuit reduces input bias current

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm reel packaging and tape specifications. Ensure compatibility with the required thermal management strategy due to the exposed paddle design. Confirm that the component meets all applicable environmental standards before integration into final assemblies.

Selection Notes

Select this component for applications requiring high speed combined with low noise and distortion. Consider the ±5 V to ±16 V supply range when designing power rails. Evaluate the need for the exposed paddle connection to ensure optimal thermal dissipation and heat transfer to the negative supply plane.

Part Context

This part belongs to the ADA4898 series of high-speed operational amplifiers. It shares core architectural features with the single-channel ADA4898-1 variant but provides two independent channels in one package. The series utilizes proprietary bipolar processing technology to achieve its performance characteristics.

Replacement Considerations

The ADA4898-1 serves as the single-channel equivalent within the same family.
