Overview
The AD8542ARUZ is a dual-channel, low-voltage micro-power CMOS voltage feedback operational amplifier. It features a gain-bandwidth product of 1.1 MHz and a slew rate of 0.8 V/μs with a quiescent current of 85 μA per amplifier at 5 V. The device supports single or dual power supplies ranging from +2.3 V to +5.5 V. It offers rail-to-rail input and output capabilities, with an operating temperature range spanning -40°C to +125°C.
Feature Summary
- Rail-to-rail input and output swing capability for maximum dynamic range
- Very low input bias current in the pA range suitable for high-impedance sources
- Extended industrial operating temperature range from -40°C to +125°C
- Unit-gain stable design optimized for general-purpose applications
Applications
- Smoke, gas, and environmental sensors
- Audio outputs
- Active filters and ASIC input or output amplifiers
- Sensor interfaces and portable equipment
Procurement Notes
Verify the manufacturer designation UMW against the official datasheet documentation provided. Confirm that the package type matches the required TSSOP-8 footprint specifications. Ensure the electrical characteristics align with the specified supply voltage and temperature ranges before integration into the final design.
Selection Notes
Select this component when low power consumption and rail-to-rail performance are critical. The 1.1 MHz bandwidth and 0.8 V/μs slew rate support moderate-speed signal processing. Verify PCB layout requirements to minimize surface leakage effects due to the extremely low input bias current specification.
Part Context
This part belongs to the AD854x family of low voltage micro power CMOS operational amplifiers. The family includes single (AD8541), dual (AD8542), and quad (AD8544) configurations. All models share similar electrical characteristics and are designed for general-purpose applications requiring optimal performance within a wide supply voltage range.
Replacement Considerations
Compatible substitutes include AD8542ARMZ and AD8542ARU. Verify pinout compatibility and ensure the replacement meets the same electrical specifications for gain-bandwidth product, slew rate, and supply voltage range.
