AD8532ARU

Overview

The AD8532ARUZ is a dual-channel, single-supply operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities with a high output drive current of ±250 mA. The device operates on a supply voltage range of 2.7 V to 6 V and consumes 750 μA per amplifier at 5 V. Key electrical parameters include a gain bandwidth product of 3 MHz, a slew rate of 5 V/μs, an input offset voltage of 25 mV, and an input bias current of 5 pA. It is specified over an extended industrial temperature range of −40°C to +85°C.

Feature Summary

• Features rail-to-rail input and output swing for maximum dynamic range in single-supply systems.
• Provides high output drive capability of ±250 mA suitable for resistive or capacitive loads.
• Operates without phase reversal when inputs are driven beyond the common-mode range.
• Maintains stability while driving heavy capacitive loads such as those found in LCD panels.

Applications

• Multimedia audio amplification
• LCD drivers
• ASIC input or output buffering
• Headphone drivers

Procurement Notes

Verify the specific package suffix RU corresponds to the 8-lead TSSOP configuration required for your PCB layout. Confirm that the operating environment remains within the specified -40°C to +85°C temperature range. Ensure external circuitry includes necessary protection against input overvoltage exceeding supply rails by more than 0.6 V, as internal current limiting is absent.

Selection Notes

Select this component when high output current drive is required alongside low power consumption. The rail-to-rail I/O characteristic makes it suitable for buffering CMOS DACs or ASICs where full signal swing is necessary. Consider thermal dissipation limits if driving heavy loads near the maximum junction temperature of 150°C.

Part Context

This part belongs to the AD853x family of low-cost, single-supply amplifiers, which includes the single-channel AD8531 and quad-channel AD8534 variants. All members share identical electrical characteristics and pinout compatibility within their respective channel counts. The family is designed for applications requiring high output current and low distortion in portable and battery-powered devices.

Replacement Considerations

Direct substitutes within the same family include the AD8531 (single channel) and AD8534 (quad channel). Other packages for the AD8532 include the 8-lead SOIC (AD8532AR) and 8-lead MSOP (AD8532ARMZ).
