ADA4899-1YCPZ-R2

Overview

The ADA4899-1YCPZ-R2 is a single-channel, unity-gain stable voltage feedback operational amplifier manufactured by Analog Devices Inc. It features ultralow noise of 1 nV/√Hz and ultralow distortion of −117 dBc at 1 MHz. The device provides a −3 dB bandwidth of 600 MHz and a slew rate of 310 V/μs with a maximum input offset voltage of 230 μV. It operates on a supply voltage range of 5 V to 12 V, drawing 14.7 mA of quiescent current. The component includes an input bias current cancellation mode via the DISABLE pin and is housed in an 8-lead LFCSP package.

Feature Summary

• Ultralow noise and distortion performance suitable for high-resolution systems
• High-speed operation with wide bandwidth and fast slew rate
• Input bias current cancellation mode for reduced DC errors
• Dedicated feedback pin design to isolate capacitive loads

Applications

• Analog-to-digital drivers
• Instrumentation
• Filters
• IF and baseband amplifiers
• DAC buffers

Procurement Notes

Verify the specific ordering suffix YCPZ-R2 against the manufacturer's official documentation to confirm the package type (LFCSP) and reel packaging configuration. Ensure that the required operating temperature range of −40°C to +125°C aligns with the system environment. Confirm that the supply voltage requirements fall within the specified 5 V to 12 V limits before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring both high speed and precision, such as driving 16-bit or 18-bit ADCs. The low noise density and high open-loop gain make it suitable for applications demanding minimal signal degradation. Consider the available disable feature if time-interleaved multiplexing or power reduction during idle states is necessary for the system architecture.

Part Context

This part belongs to the ADA4899 series of high-speed operational amplifiers from Analog Devices. It utilizes the proprietary XFCB process to achieve its performance metrics. The YCPZ-R2 designation indicates a specific variant within the family, distinguished by its lead-free LFCSP packaging and tape-and-reel delivery format, differentiating it from SOIC variants or non-reel versions.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains the required 600 MHz bandwidth and 1 nV/√Hz noise specifications to ensure circuit performance parity.
