Product details

6.5 MHz GBW and 12V/µs slew rate — what they buy the design

This combination supports signal conditioning up to several hundred kilohertz with decent large-signal fidelity — enough for audio line-level stages, active filters in industrial sensors, or ADC front-end buffering where 6.5 MHz GBW keeps the loop gain healthy below 100 kHz. The 12V/µs slew rate means a 10 V peak-to-peak output step settles in under 1 µs, avoiding slew-induced distortion in fast pulse or waveform applications. Supply range spans 9 V to 36 V, letting it run from a single 12 V or 24 V industrial rail, or split ±5 V to ±18 V supplies. Quiescent current is 1.8 mA per amplifier — moderate for the speed class, but worth noting if the board packs four or more channels and the power budget is tight.

Package and supply rails for the PCB layout

The 9 V minimum supply means it won't run on a 5 V rail alone; plan for at least a 9 V supply or split ±5 V.

Frequently asked questions

What is the difference between ADA4075-2ARZ and ADA4075-2ARZ-R7?

The -R7 suffix indicates Tape & Reel packaging (7-inch reel, 1000-piece quantity typical), while the base ADA4075-2ARZ is the same silicon offered in tube or cut-tape form. Electrically and functionally they are identical.

Is ADA4075-2ARZ-R7 RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive.

Can I use ADA4075-2ARZ-R7 in audio applications?

The 6.5 MHz gain-bandwidth product and 12V/µs slew rate are adequate for line-level audio stages, active crossovers, and headphone drivers within its output current capability (40 mA per channel). The 200 µV input offset is acceptable for most audio paths, though precision audio designs may prefer lower-offset alternatives.

What are the equivalent or replacement parts for ADA4075-2ARZ-R7?

The AD8599ARZ-REEL7 is a dual general-purpose op amp with a 10 MHz GBW and 16V/µs slew rate — a higher-speed sibling in the same 8-SOIC footprint. The ADA4000-4ARZ-R7 is a quad JFET-input op amp (5 MHz, 20V/µs) for applications needing lower input bias current. Neither is a direct pin-compatible replacement without verifying the circuit's speed and input bias requirements.
