AD8567ACP-REEL7

Overview

The AD8567ACPZ-REEL7 is a quad operational amplifier from Analog Devices, built on an advanced high-voltage CBCMOS process. It features rail-to-rail input and output capabilities with a supply voltage range of 4.5 V to 16 V. Key electrical parameters include a maximum offset voltage of 10 mV, a slew rate of 6 V/µs, and a gain-bandwidth product of 5 MHz. The device provides 35 mA continuous output current and up to 250 mA peak current. It operates within a temperature range of -40°C to +85°C and is housed in a 16-lead LFCSP package.

Feature Summary

• Rail-to-rail input and output operation for single-supply applications
• High capacitive load drive capability without compensation
• Immunity to output phase reversal during overvoltage conditions
• Low total harmonic distortion plus noise performance

Applications

• LCD grayscale reference buffers
• LCD VCOM driver circuits
• Portable electronics
• Automotive infotainment systems

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the reel packaging configuration required for your assembly line. Confirm that the 16-lead LFCSP (CP-16-23) package option matches your PCB footprint design. Ensure the component meets RoHS compliance standards as indicated by the Z suffix in the base part number. Cross-reference the manufacturer's latest datasheet revision H for any updates to thermal resistance or absolute maximum ratings before finalizing procurement.

Selection Notes

Select this component when driving large capacitive loads typical in LCD panel interfaces. The rail-to-rail input stage allows full signal swing utilization near ground and positive supply rails. Consider the 35 mA continuous output current for direct drive requirements. Verify that the 5 MHz bandwidth and 6 V/µs slew rate meet the dynamic signal requirements of the application circuit.

Part Context

This device belongs to the AD8565/AD8566/AD8567 family of low-cost, single-supply operational amplifiers. While the AD8565 is a single amplifier and the AD8566 is dual, the AD8567 integrates four amplifiers in one package. All variants share the same underlying CBCMOS technology and electrical characteristics, differing primarily in channel count and physical package dimensions.

Replacement Considerations

Official substitutes include AD8567ARUZ and AD8567ACPZ-REEL. Note that the ARUZ variant utilizes a 14-lead TSSOP package, requiring layout adjustments compared to the 16-lead LFCSP of the ACPZ version. Electrical specifications remain consistent across these package options within the same series.

FAQ

Does the AD8567ACPZ-REEL7 experience output phase reversal?

No, the device is immune to output phase reversal even if the input common-mode voltage exceeds the supply rails.

How should the exposed thermal pad be connected in the LFCSP package?

The exposed pad must be soldered to an area electrically isolated from ground or connected directly to the positive supply (V+) to ensure safe operation and optimal heat dissipation.
