Overview
The AD8531AKS-REEL7 is a single rail-to-rail input/output operational amplifier from Analog Devices, designed for single-supply operation between 2.7 V and 6 V. It features a high output drive current of ±250 mA, making it suitable for driving resistive or capacitive loads. The device offers a gain bandwidth product of 3 MHz and a slew rate of 5 V/μs at 5 V supply. Supply current is typically 750 μA per amplifier. It operates over an extended industrial temperature range of −40°C to +85°C and is housed in a 5-lead SC-70 package.
Feature Summary
- Single-supply operation with rail-to-rail input and output capabilities
- High output drive current of ±250 mA for heavy load applications
- Low supply current consumption of approximately 750 μA per amplifier
- Unity gain stable with no phase reversal
Applications
- Multimedia audio amplification
- LCD drivers
- ASIC input or output buffering
- Headphone drivers
Procurement Notes
Verify the specific ordering suffix AKS corresponds to the 5-lead SC-70 package configuration. Confirm that the REEL7 designation indicates tape and reel packaging. Ensure the component meets the required extended industrial temperature range specifications for your application environment before finalizing procurement.
Selection Notes
Select this amplifier when high output current drive is necessary alongside low power consumption. The rail-to-rail input and output characteristics allow for maximum dynamic range in single-supply systems. Consider the thermal resistance of the SC-70 package when designing for high load currents to ensure junction temperatures remain within safe operating limits.
Part Context
This component belongs to the AD853x family, which includes single (AD8531), dual (AD8532), and quad (AD8534) versions. All variants share similar electrical characteristics, including the 250 mA output drive and CMOS architecture. The AD8531 is the single-channel version, providing a cost-effective solution for applications requiring only one high-current amplifier channel.
Replacement Considerations
Direct replacements within the same family include the AD8532 and AD8534, provided pin compatibility and channel count requirements are met. Other packages such as SOT-23 (RJ suffix) or SOIC (R suffix) offer functional equivalence but require layout adjustments due to different pin configurations.
