ADA4857-2YCPZ-RL

Overview

The Analog Devices ADA4857-2YCPZ-RL is a dual-channel, unity-gain stable, high-speed voltage feedback operational amplifier. It features an 850 MHz bandwidth and a 2800 V/μs slew rate in the LFCSP package. The device operates on a wide supply voltage range of 4.5 V to 10.5 V with a quiescent current of approximately 5 mA per amplifier. It incorporates a power-down feature for reduced consumption and is housed in a 4 mm × 4 mm 16-lead LFCSP package.

Feature Summary

• High-speed performance with 850 MHz bandwidth and 2800 V/μs slew rate
• Low noise density of 4.4 nV/√Hz and low harmonic distortion
• Integrated power-down pin for reducing quiescent current
• Extended industrial operating temperature range from -40°C to +125°C

Applications

• Instrumentation systems
• IF and baseband amplifiers
• Active filters
• ADC drivers
• DAC buffers

Procurement Notes

Verify the specific ordering suffix matches the required reel packaging configuration. Confirm that the component corresponds to the dual-channel variant rather than the single-channel version. Ensure the lead finish and RoHS compliance align with your manufacturing requirements before finalizing procurement orders.

Selection Notes

Select this component when high dynamic range and precision are required alongside speed. The dual-channel architecture reduces board space compared to using two separate single-channel devices. Consider the exposed paddle thermal management capabilities for efficient heat dissipation in dense PCB layouts.

Part Context

This part belongs to the ADA4857 family of ultralow distortion, low power, low noise, high-speed op amps. It utilizes Analog Devices' proprietary XFCB process technology to achieve its performance metrics. The dual-channel version provides two independent amplifiers within a single compact surface-mount package.

Replacement Considerations

Check for direct functional equivalents such as the ADA4896-2ACPZ-RL or other high-speed dual op amps from Analog Devices. Verify pin compatibility and electrical specifications against the original design requirements before substituting.
