Overview
The AD8542AR-REEL is a dual-channel CMOS rail-to-rail general-purpose operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical supply current of 45 µA per amplifier. The device features a gain-bandwidth product of 1 MHz, a slew rate up to 0.92 V/µs at 5 V, and an input bias current as low as 4 pA. It is specified over an extended industrial temperature range of -40°C to +125°C and is housed in an 8-lead TSSOP package.
Feature Summary
- Rail-to-rail input and output capability for maximum dynamic range in single-supply systems
- Very low input bias current suitable for high source impedance applications
- Unity-gain stable design without phase reversal issues
- Optimized AC performance at lower supply voltages
Applications
- ASIC input or output amplifiers
- Sensor interfaces
- Piezoelectric transducer amplifiers
- Medical instrumentation
- Portable battery-powered systems
Procurement Notes
Verify the specific ordering suffix matches the required tape and reel packaging quantity. Confirm RoHS compliance status and ensure the component meets automotive qualification requirements if applicable to the target environment. Cross-reference the datasheet revision to validate electrical characteristics against the manufacturing date code.
Selection Notes
Select this component when low power consumption is critical alongside moderate bandwidth requirements. The dual-channel configuration reduces board space compared to single-channel alternatives. Ensure the application benefits from rail-to-rail signal swing and verify that the input bias current specifications align with the source impedance of the connected circuitry.
Part Context
This part belongs to the AD854x family of CMOS amplifiers, which includes single (AD8541), dual (AD8542), and quad (AD8544) channel variants. The series is designed to provide improved performance over previous generations by offering higher output current and better low-voltage operation while maintaining ultra-low quiescent current levels.
Replacement Considerations
Direct functional equivalents within the same package include the AD8542ARMZ and AD8542ARUZ. Verify pin compatibility and thermal resistance values when substituting between SOIC, MSOP, and TSSOP packages.
