Overview
The AD8594AR-REEL is a quad, single-supply, rail-to-rail input and output operational amplifier manufactured by Analog Devices Inc. It features a power-saving shutdown mode that reduces total supply current to less than 1 μA when all amplifiers are deactivated. The device operates on a single supply voltage ranging from 2.5 V to 6 V. Key electrical specifications include a gain bandwidth product of 3 MHz, a slew rate of 5 V/μs, and an output current capability of ±250 mA per channel. Input bias current is extremely low at 50 pA typical.
Feature Summary
- Quad configuration with a single master shutdown function for the entire package
- Rail-to-rail input and output operation on a single supply
- High output drive capability of ±250 mA per channel
- Extremely low shutdown supply current below 1 μA
Applications
- Mobile communication handset audio
- PCMCIA/modem line driving
- Battery-powered instrumentation
- Data acquisition systems
- LCD display reference level drivers
Procurement Notes
Verify the specific ordering suffix 'AR' corresponds to the 16-lead narrow SOIC package as defined in the manufacturer's documentation. Confirm the '-REEL' designation indicates tape and reel packaging rather than cut tape or tube formats. Ensure the component meets the required industrial temperature range specifications for the intended application environment.
Selection Notes
Select this component when a quad amplifier configuration is required alongside a unified shutdown control mechanism. The high output current capability makes it suitable for driving heavy capacitive loads directly. Verify that the single-supply voltage range aligns with the system power rails and that the CMOS input characteristics match the source impedance requirements.
Part Context
This part belongs to the AD859x family of single-supply operational amplifiers, which includes the AD8591 (single), AD8592 (dual), and AD8594 (quad). All members share identical electrical characteristics and architecture but differ in channel count and physical package configurations. The AD8594 specifically provides four independent amplifiers controlled by one shutdown pin.
Replacement Considerations
Direct substitutes within the same family include the AD8591ARZ and AD8592ARZ, provided the channel count difference is acceptable for the circuit design.
