AD8568ART-R2

Overview

The AD8568ART-R2 is a dual buffer amplifier from Analog Devices, packaged in a 6-lead SOT-23. It operates on a single supply voltage ranging from 4.5 V to 16 V. The device features rail-to-rail input and output capabilities with a maximum offset voltage of 10 mV and a slew rate of 6 V/µs. It provides 35 mA continuous output current and can drive capacitive loads up to 1 µF. The operational temperature range extends from -40°C to +85°C.

Feature Summary

• Single-supply operation with rail-to-rail input and output swing
• High output drive capability supporting 35 mA continuous current
• Stable when driving large capacitive loads up to 1 µF
• Immune to output phase reversal under overvoltage conditions

Applications

• LCD reference drivers
• Portable electronics
• Communications equipment

Procurement Notes

Verify the component status as obsolete before procurement. Confirm the specific suffix RT-6 corresponds to the 6-lead SOT-23 package. Ensure ESD precautions are observed during handling due to electrostatic sensitivity. Check for lead-free compliance if required by application standards.

Selection Notes

Select this component for applications requiring high capacitive load drive and rail-to-rail performance on a single supply. Consider the 6-lead SOT-23 package constraints for thermal dissipation. Evaluate the 10 mV max offset voltage against system accuracy requirements. Verify that the 35 mA continuous current limit meets the load demands.

Part Context

This part belongs to the AD8568/AD8569/AD8570 family of low-cost, single-supply buffer amplifiers built on an advanced high voltage CBCMOS process. While the AD8568 contains two buffers, the AD8569 includes four, and the AD8570 includes eight. All variants share similar electrical characteristics optimized for LCD monitor applications.
