Overview
The AD8534ARZ is a quad, single-supply operational amplifier manufactured by UMW. It features rail-to-rail input and output capabilities with a high output drive current of ±250 mA. The device operates on a single supply voltage ranging from 2.7 V to 6 V. Key electrical specifications include a gain-bandwidth product of 3 MHz, a slew rate of 5 V/µs, and a typical supply current of 750 µA per amplifier at 5 V. Input bias current is specified as low as 5 pA. The component is available in a 14-lead SOP package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides high output drive capability suitable for resistive or capacitive loads
- Features rail-to-rail input and output swing for maximum dynamic range
- Ensures unity-gain stability without phase reversal issues
- Maintains low power consumption while delivering significant load current
Applications
- Multimedia audio amplification
- LCD drivers
- ASIC input or output buffering
- Headphone drivers
Procurement Notes
Verify the manufacturer designation matches UMW (UMD Semiconductor) rather than Analog Devices when sourcing this specific part number. Confirm the package type corresponds to the 14-lead SOP configuration. Ensure the ordering suffix aligns with the required delivery mode, such as tape and reel quantities if applicable. Cross-reference the datasheet revision to confirm electrical characteristics match design requirements.
Selection Notes
Select this component for applications requiring high current drive in single-supply systems. The rail-to-rail I/O allows for optimal signal swing near supply rails. Consider the 3 MHz bandwidth and 5 V/µs slew rate for moderate-speed signal processing. Verify that the ±250 mA output current meets load demands without exceeding thermal limits in the chosen package.
Part Context
This part belongs to the AD853x family of low-cost, single-supply amplifiers. The series includes single-channel (AD8531), dual-channel (AD8532), and quad-channel (AD8534) variants. All members share similar electrical characteristics, including high output current and rail-to-rail performance, allowing for flexible pin-compatible design scaling across different channel counts.
Replacement Considerations
Direct substitutes within the same family include AD8531ARZ and AD8532ARZ for reduced channel counts. Other quad-channel alternatives may require verification of pin compatibility and electrical parameter alignment.
