ADA4853-2YCPZ-R2

Overview

The ADA4853-2YCPZ-R2 is a dual-channel, low-power, rail-to-rail output video operational amplifier manufactured by Analog Devices Inc. Designed for single-supply operation within a 2.65 V to 5 V range, it delivers high-speed performance characterized by a 100 MHz bandwidth and a 120 V/μs slew rate at 5 V. The device features ultralow power consumption with a quiescent current of 1.4 mA per amplifier and an ultralow disable current of 0.1 μA. It provides excellent video fidelity with a differential gain of 0.2% and differential phase of 0.1°. Packaged in a 16-lead LFCSP_WQ, it operates over an industrial temperature range of -40°C to +105°C.

Feature Summary

• Ultralow power disable mode reduces supply current to less than 1.5 μA maximum, ideal for battery-powered applications.
• Rail-to-rail output capability allows the signal to swing within 200 mV of either supply rail.
• High-speed voltage feedback architecture ensures accurate standard definition video processing.
• True single-supply operation supports input signals extending below the negative rail.

Applications

• Automotive infotainment systems
• Portable multimedia players
• Video cameras and digital still cameras
• Clock buffer circuits

Procurement Notes

Verify that the specific ordering suffix matches the required package type and reel quantity. Confirm the operating temperature range aligns with system requirements, as the 16-lead LFCSP variant supports up to +105°C. Ensure proper ESD handling protocols are followed during assembly due to the surface-mount nature of the component.

Selection Notes

Select this component when designing portable or automotive electronics requiring low power consumption alongside high-speed signal processing. The dual-channel configuration is suitable for stereo audio buffering or dual-video line driving. Consider the 16-lead LFCSP package for compact board layouts requiring efficient thermal dissipation.

Part Context

This part belongs to the ADA4853 series of low-cost, high-speed video amplifiers from Analog Devices. The series includes single-channel (ADA4853-1) and triple-channel (ADA4853-3) variants. The ADA4853-2 specifically integrates two independent amplifiers into one package, sharing common power and ground connections while maintaining individual disable control capabilities.

Replacement Considerations

Direct substitutes include other parts within the ADA4853 family such as the ADA4853-1 or ADA4853-3, provided channel count differences are acceptable. Verify pinout compatibility and thermal resistance specifications before substituting with generic video op-amps.

FAQ

How does the disable function operate on the ADA4853-2?

The device features dedicated DISABLE pins for each channel. Applying a logic low (0 V) activates the ultralow power mode, reducing quiescent current to under 1.5 μA and placing the outputs in a high-impedance state.

What is the input common-mode voltage range?

The input common-mode voltage range extends from 200 mV below the negative supply rail to within 1.2 V of the positive supply rail, allowing for true single-supply operation.
