AD8513ARUZ-REEL

Overview

The AD8513ARUZ-REEL is a quad precision JFET operational amplifier from Analog Devices. It features an 8 MHz gain bandwidth product, a 20 V/µs slew rate, and a maximum input offset voltage of 400 µV. The device operates on dual supplies ranging from ±5 V to ±15 V with a typical supply current of 2.75 mA for the quad configuration. It exhibits low noise density of 8 nV/√Hz at 1 kHz and maintains stability when driving capacitive loads up to 1000 pF without oscillation.

Feature Summary

• Provides high DC precision combined with fast settling time and low distortion suitable for demanding measurement applications.
• Maintains stable performance and does not exhibit output phase reversal even when input voltages exceed the common-mode range.
• Capable of driving substantial capacitive loads directly while preserving signal integrity and transient response.

Applications

• Instrumentation systems requiring high accuracy
• Multipole filter circuits
• Photodiode amplification
• Precision current measurement using shunts

Procurement Notes

Verify that the specific ordering suffix matches the required package type and reel quantity. Confirm the grade (A or B) aligns with the necessary offset voltage specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision to validate all electrical parameters against your design constraints.

Selection Notes

Select this component when a quad channel configuration is required alongside JFET input characteristics. It is appropriate for designs needing wide dynamic range and low bias currents. Consider the extended industrial temperature range if operation outside standard limits is necessary. Evaluate the trade-off between the quad channel count and the slightly higher supply current compared to single-channel variants.

Part Context

This part belongs to the AD8510/AD8512/AD8513 family of precision JFET amplifiers. While the AD8510 is a single channel and the AD8512 is a dual channel, the AD8513 integrates four independent amplifiers in one package. All members share identical core electrical specifications regarding noise, bandwidth, and offset characteristics.

Replacement Considerations

Direct substitutes within the same family include the AD8510ARUZ-REEL for single-channel needs and the AD8512ARUZ-REEL for dual-channel applications. These parts share the same pinout compatibility and electrical performance profiles as the AD8513.

FAQ

Does the AD8513 suffer from output phase reversal?

No, unlike many older JFET amplifiers, the AD8513 does not exhibit output phase reversal when input voltages exceed the maximum common-mode voltage range.

What is the maximum capacitive load the AD8513 can drive?

The AD8513 is unconditionally stable and capable of driving a capacitive load of up to 1000 pF without oscillation in a unity-gain configuration.
