ADA4856-3YCPZ-RL

Overview

The ADA4856-3YCPZ-RL is a triple, single-supply, high-speed video amplifier with a fixed internal gain of +2. It features rail-to-rail output swing and operates on supply voltages from 3 V to 5.5 V. Key performance metrics include a -3 dB bandwidth of 225 MHz at 2 V p-p, a slew rate of 800 V/μs, and a settling time of 5 ns to 0.1% for a 2 V step. The device draws a typical quiescent current of 7.8 mA per amplifier and includes a power-down feature that reduces current consumption to approximately 1 mA.

Feature Summary

• Voltage feedback architecture with fixed internal gain of +2
• Rail-to-rail output stage capable of swinging within 200 mV of either supply rail
• Wide input common-mode voltage range extending 0.2 V below the negative rail
• Integrated power-down function for reduced standby current consumption

Applications

• Professional video systems
• Consumer video equipment
• Imaging applications
• Instrumentation circuits
• Base station infrastructure

Procurement Notes

Verify the specific ordering suffix YCPZ-RL against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required operating temperature range of -40°C to +105°C. Confirm that the 16-lead LFCSP footprint matches the target PCB layout constraints. Validate that the fixed gain configuration meets the system requirements without additional external resistors.

Selection Notes

Select this component when a fixed gain of +2 is required for high-speed signal processing. The device is suitable for single-supply designs operating between 3 V and 5.5 V. Consider the low noise density of 14 nV/√Hz for sensitive signal paths. The integrated power-down pin allows for energy management in battery-operated or power-sensitive applications.
