Overview
The AD8619WARZ-R7 is a quad, low voltage, micropower CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates from a single supply of 1.8 V to 5.5 V or dual supplies of ±0.9 V to ±2.5 V. Key electrical specifications include a maximum offset voltage of 2.2 mV, a maximum input bias current of 1 pA, and a typical voltage noise density of 22 nV/√Hz at 10 kHz. The device offers a gain bandwidth product of 400 kHz and consumes a maximum of 50 μA per amplifier across the operating temperature range of -40°C to +125°C.
Feature Summary
- Rail-to-rail input and output operation enables full signal swing in low voltage single-supply systems.
- Micropower consumption with extremely low input bias current suitable for portable applications.
- Low noise performance minimizes signal degradation in high-gain circuits.
- Automotive qualification ensures reliability under demanding environmental conditions.
Applications
- Battery-powered instrumentation
- Multipole filters
- Current shunt sense
- ADC predrivers
Procurement Notes
Verify that the ordering suffix R7 corresponds to the reel packaging format required for automated assembly processes. Confirm the W designation indicates automotive qualification if specific industry standards are mandated. Ensure the SOIC-14 package option matches the intended PCB footprint constraints. Cross-reference the RoHS compliance status with current regulatory requirements for the target market.
Selection Notes
Select this component when a quad configuration is necessary to minimize board space compared to single or dual amplifiers. Consider the 400 kHz gain bandwidth product for applications requiring moderate speed with low power consumption. Evaluate the 2.2 mV maximum offset voltage against system accuracy requirements. Verify that the 1.8 V minimum supply voltage aligns with the available power rails in the design.
Part Context
This part belongs to the AD8613/AD8617/AD8619 family of low cost micropower op amps. The AD8619 specifically provides four independent amplifiers in a single package. The W suffix denotes automotive qualification, while the Z suffix indicates RoHS compliance. The R7 suffix specifies tape and reel packaging for surface mount technology.
Replacement Considerations
The AD8619ARZ-R7 serves as the commercial grade equivalent without automotive qualification. Other family members like the AD8617 offer dual configurations in smaller packages.
