Overview
The AD8608ARZ-REEL7 is a quad precision CMOS operational amplifier from Analog Devices, featuring rail-to-rail input and output capabilities. It utilizes DigiTrim technology for superior offset voltage performance without laser trimming. Key electrical specifications include a maximum offset voltage of 75 µV at 3.5 V supply, a unity gain bandwidth of 10 MHz, and a slew rate of 5 V/µs. The device operates on a single supply ranging from 2.7 V to 5.5 V and is housed in a 14-lead SOIC package.
Feature Summary
- Quad channel configuration with rail-to-rail input and output
- DigiTrim patented trimming technique for high precision
- Low noise density of 8 nV/√Hz
- Unity gain stable operation
Applications
- Photodiode amplification
- Battery-powered instrumentation
- Multipole filters
- High impedance sensors
- Barcode scanners
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current product selector to ensure package availability and tape-and-reel packaging status. Confirm that the component meets RoHS compliance requirements for the intended manufacturing process.
Selection Notes
Select this component when multiple precision channels are required in a compact surface-mount footprint. Ensure the application benefits from the low input bias current and wide signal bandwidth provided by the CMOS architecture.
Part Context
This part belongs to the AD8605/AD8606/AD8608 family of precision, low-noise, CMOS, rail-to-rail input/output operational amplifiers. The AD8608 specifically provides four independent amplifier circuits within a single package, distinguishing it from the single-channel AD8605 and dual-channel AD8606 variants.
Replacement Considerations
Official substitutes within the same family include the AD8605 and AD8606, which offer identical electrical characteristics but with different channel counts. Verify pin compatibility and package dimensions before substitution.
FAQ
Does the AD8608 exhibit output phase reversal?
No, the AD860x series does not exhibit output phase reversal even for inputs exceeding the supply voltage by more than 2 V.
What is the maximum input offset voltage for the AD8608?
The maximum input offset voltage is 75 µV when the supply voltage is 3.5 V and the common-mode voltage is 2.7 V.
