ADA4853-1AKSZ-R7

Overview

The ADA4853-1AKSZ-R7 is a low-power, high-speed voltage feedback operational amplifier with rail-to-rail output and ultralow power disable functionality. It operates on a single supply ranging from 2.65 V to 5 V, consuming 1.4 mA per amplifier in active mode and less than 1.5 μA when disabled. The device features a 100 MHz −3 dB bandwidth and a 120 V/μs slew rate at 5 V. It offers excellent video performance with 0.2% differential gain and 0.1° differential phase. Packaged in a 6-lead SC70, it supports an operating temperature range of −40°C to +85°C.

Feature Summary

• Ultralow power disable mode reduces supply current to under 1.5 μA for battery-powered applications.
• Rail-to-rail output stage swings within 200 mV of either supply rail.
• True single-supply operation allows input signals to extend 200 mV below the negative rail.
• High-speed performance includes 100 MHz bandwidth and 120 V/μs slew rate.

Applications

• Automotive infotainment systems
• Portable multimedia players
• Video cameras
• Digital still cameras
• Clock buffer

Procurement Notes

Verify the specific ordering suffix AKSZ-R7 against the manufacturer's official documentation to confirm package type and reel specifications. Ensure the component meets the required -40°C to +85°C operating temperature range for your application environment. Cross-reference the datasheet revision G specifications for accurate electrical parameters before finalizing procurement.

Selection Notes

Select this component for designs requiring low quiescent current alongside high-speed signal processing. The 6-lead SC70 package is suitable for space-constrained portable electronics. Consider the 1.4 mA active current consumption and the availability of the disable pin for power management strategies in battery-operated devices.

Part Context

This part belongs to the ADA4853 series of low-cost, high-speed video amplifiers manufactured by Analog Devices Inc. The series includes single-channel (ADA4853-1), dual-channel (ADA4853-2), and triple-channel (ADA4853-3) variants. The ADA4853-1 specifically provides a single amplifier in a compact surface-mount package designed for consumer and automotive video applications.

Replacement Considerations

Direct substitutes include other parts within the ADA4853 family such as the ADA4853-2 or ADA4853-3 if channel count requirements change. Verify pin compatibility and thermal characteristics when replacing with different package options like LFCSP_WQ or TSSOP.

FAQ

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.

How does the disable function affect the output?

When the DISABLE pin is driven low (0 V), the amplifier enters a low-power state with supply current reduced to less than 1.5 μA, placing the output in a high-impedance state.
