AD8614ARTZ-REEL7

Overview

The AD8614ARTZ-REEL7 is a single-channel precision operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 5 V to 18 V and features rail-to-rail input and output capabilities. Key electrical specifications include a unity-gain bandwidth of 5.5 MHz, a slew rate of 7.5 V/µs, and an output short-circuit current capability of up to 70 mA. The device draws a typical supply current of 800 µA per amplifier and maintains an input offset voltage of 1.0 mV. It is housed in a 5-lead SOT-23 package and is specified for operation within a temperature range of -20°C to +85°C.

Feature Summary

• Utilizes high voltage extra fast complementary bipolar (HV XFCB) process technology with trench-isolated transistors to minimize internal parasitic capacitance.
• Provides rail-to-rail input and output swing to maximize dynamic range and control compared to standard video amplifiers.
• Capable of driving large capacitive loads while maintaining stability without requiring external compensation components.
• Features built-in protection against output phase reversal when input voltages remain within the supply rails.

Applications

• LCD gamma and VCOM drivers
• Portable instrumentation systems
• Direct access arrangement circuits

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as the REEL7 designation indicates tape and reel delivery. Confirm RoHS compliance status through the manufacturer's documentation, as indicated by the Z suffix in the part number. Ensure the selected component meets the specific thermal resistance requirements for the 5-lead SOT-23 package during integration.

Selection Notes

Select this component for designs requiring high output drive current and wide supply voltage ranges up to 18 V. The low supply current makes it suitable for densely packed or portable applications where power efficiency is critical. Consider the 5.5 MHz bandwidth and 7.5 V/µs slew rate for signal processing tasks requiring moderate speed and precision.

Part Context

This device belongs to the AD8614/AD8644 family of single-supply operational amplifiers. While the AD8614 provides a single channel, the quad version (AD8644) offers four channels in larger packages. Both variants share the same HV XFCB process and core performance characteristics, optimized specifically for LCD monitor applications and general-purpose signal conditioning.
