Product details

The zero-drift architecture delivers a maximum input offset voltage of 1 µV and typical input bias current of 30 pA, making this a natural fit for precision instrumentation, thermocouple amplifiers, and weigh-scale front ends that must maintain accuracy across a wide thermal swing. Rail-to-rail output swing and a 2.5 MHz gain-bandwidth product with 1 V/µs slew rate give it enough bandwidth for low-frequency sensor conditioning without sacrificing DC precision.

Each channel draws 850 µA supply current, which is moderate for a zero-drift amplifier — not the lowest-power option, but a reasonable trade-off for the 1 µV offset stability.

8-SOIC package — standard footprint, no assembly surprises

The listed shipping medium is Tube; if you need Tape & Reel for automated assembly, verify the reel option with your order.

Frequently asked questions

Can I use AD8629TRZ-EP as a replacement for AD8628?

The AD8628 is a single-channel zero-drift amplifier with the same 2.5 MHz GBW, 1 V/µs slew rate, and 1 µV offset. The AD8629TRZ-EP is the dual-channel version, so it can replace two AD8628s in a design, but the pinout and channel count differ.

What are the best alternatives to AD8629TRZ-EP?

If the extended temperature is not required, the ARMZ is a direct dual-channel substitute.
