Overview
The AD8531ARTZ is a single-supply, rail-to-rail input/output operational amplifier manufactured by UMW. It operates on a supply voltage range of 2.7 V to 6 V and provides a high output drive current of ±250 mA. The device features 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 at 5 V. Input bias current is limited to 50 pA (max) at 25°C. The component is unity-gain stable and guarantees operation from both 3 V and 5 V single supplies.
Feature Summary
- Single-supply operation with rail-to-rail input and output capabilities
- High output drive current of ±250 mA for resistive or capacitive loads
- Low supply current consumption of 750 μA per amplifier
- Unity-gain stability with no phase reversal
Applications
- Multimedia audio amplification
- LCD drivers
- ASIC input or output amplifiers
- Headphone drivers
Procurement Notes
Verify the manufacturer marking matches UTD Semiconductor Co., Limited specifications. Confirm the package type corresponds to SOP-8 as indicated by the ARTZ suffix in the ordering information table. Ensure the component meets the required operating temperature range of -40°C to +85°C for your specific application environment.
Selection Notes
Select this component when a single-supply amplifier requires high output current capability without sacrificing low power consumption. The rail-to-rail input and output ranges make it suitable for buffering wide-swing devices like CMOS DACs or ASICs in single-supply systems where maximizing dynamic range is critical.
Part Context
The AD8531ARTZ belongs to the AD853x family of low-cost, single-supply amplifiers produced by UMW. This family includes dual (AD8532) and quad (AD8534) variants sharing similar electrical characteristics. The AD8531 specifically offers a single amplifier channel in an 8-lead SOP package, designed for applications requiring moderate channel density with high drive strength.
Replacement Considerations
Direct substitutes within the same family include the AD8532ARZ (dual channel) and AD8534ARZ (quad channel). Other pin-compatible options may exist but require verification of package dimensions and electrical parameters against the UMW datasheet.
