Overview
The AD8619WARUZ-R7 is a quad, low voltage, micropower CMOS operational amplifier from Analog Devices. It features rail-to-rail input and output capabilities, making it suitable for single-supply systems operating between 1.8 V and 5.5 V. The device offers a gain bandwidth product of 400 kHz and a maximum supply current of 50 μA per amplifier across the temperature range. It is housed in a 14-lead TSSOP package (RU-14) and is qualified for automotive applications under AEC-Q100 standards.
Feature Summary
- Rail-to-rail input and output operation enables full signal swing in low voltage single-supply environments.
- Micropower consumption with a maximum supply current of 50 μA per amplifier over the operating temperature range.
- Automotive qualification ensures reliability and controlled manufacturing for automotive application requirements.
Applications
- Battery-powered instrumentation
- Multipole filters
- Current shunt sense circuits
- ADC predrivers
Procurement Notes
Verify that the specific part number matches the required package type and automotive qualification status. Confirm RoHS compliance details as indicated in official documentation. Ensure the ordering suffix corresponds to the correct reel or cut tape packaging format intended for the assembly process.
Selection Notes
Select this component when designing portable or loop-powered instrumentation requiring low power consumption alongside precision amplification. The rail-to-rail I/O feature is critical for maximizing dynamic range in low voltage systems. Consider the 400 kHz bandwidth and micropower characteristics for applications where energy efficiency and moderate speed are prioritized.
Part Context
This component belongs to the AD8613/AD8617/AD8619 family of low cost, micropower, low noise CMOS rail-to-rail input/output operational amplifiers. The AD8619 variant specifically provides four independent amplifiers within a single integrated circuit, offering a compact solution for multi-channel signal processing tasks.
Replacement Considerations
The AD8619ARUZ-R7 serves as a commercial grade alternative without automotive qualification. Other family members include the AD8613 (single channel) and AD8617 (dual channel). Verify pin compatibility and electrical specifications before substituting.
