ADA4853-1AKSZ-R2

Overview

The ADA4853-1AKSZ-R2 is a single-channel, low-power, high-speed voltage feedback operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output capability and an ultralow power disable function. The device operates on a single supply ranging from 2.65 V to 5 V with a quiescent current of 1.4 mA per amplifier. Key electrical specifications include a 100 MHz bandwidth, a 120 V/µs slew rate, and a low input offset voltage of 1 mV. It is housed in a 6-lead SC70 package and supports an operating temperature range of −40°C to +85°C.

Feature Summary

• Ultralow power disable mode reduces supply current to less than 1.5 µA maximum.
• Rail-to-rail output stage swings within 200 mV of either supply rail.
• True single-supply operation allows input signals to extend below the negative rail.

Applications

• Portable multimedia players
• Video cameras
• Digital still cameras
• Consumer video equipment

Procurement Notes

Verify that the specific ordering suffix AKSZ-R2 corresponds to the 6-lead SC70 package variant. Confirm the component meets the required industrial temperature range of −40°C to +85°C for your application environment. Ensure the disabled state logic aligns with system power management requirements.

Selection Notes

Select this component for applications requiring high-speed signal processing with strict power constraints. The 100 MHz bandwidth and 120 V/µs slew rate support general-purpose high-speed tasks. The rail-to-rail output and wide supply range make it suitable for battery-powered portable electronics where maximizing dynamic range is critical.

Part Context

This part belongs to the ADA4853 series, which includes dual (ADA4853-2) and triple (ADA4853-3) channel variants. While the -1 variant is packaged in a 6-lead SC70, other members of the family utilize larger packages such as LFCSP_WQ or TSSOP. The series is designed for low-cost, high-performance video and portable consumer electronics applications.

Replacement Considerations

Direct functional replacements within the same package are not explicitly confirmed in the provided documentation. Verify pinout compatibility and thermal characteristics before substituting with other single-channel op-amps.
