Product details

Dual CMOS op-amp for signal conditioning in tight power budgets

The ADA4666-2ARMZ-R7 is a dual-channel CMOS operational amplifier from Analog Devices, designed for precision signal conditioning where low power consumption and rail-to-rail output swing are required. Each channel draws 630 µA supply current, making it a fit for battery-operated or multi-channel data acquisition systems. The 4 MHz gain-bandwidth product and 2 V/µs slew rate support audio-band filtering, sensor buffering, and general-purpose analog processing. Outputs swing rail-to-rail, maximizing dynamic range in low-voltage single-supply designs from 3 V to 18 V.

Temperature range and industrial deployment

The extended range also covers under-hood automotive sensor interfaces, provided the system supply stays within the 3 V to 18 V span.

Package and mounting for production

Standard MSL handling applies — store reels dry and bake before reflow if the moisture barrier bag has been breached.

Lifecycle and sourcing posture

For long-term production planning, the active status supports multi-year BOM commitments without obsolescence risk.

Frequently asked questions

What are equivalent or replacement parts for ADA4666-2ARMZ-R7?

Within the same Analog Devices family, the ADA4622-2ARMZ-R7 is a JFET-input dual op-amp with higher slew rate (23 V/µs) and lower input offset (40 µV), but it draws 700 µA per channel and operates from a 5 V supply. The ADA4691-2ACPZ-R7 is a general-purpose dual op-amp with 3.6 MHz bandwidth and 1.3 V/µs slew rate, also rail-to-rail, but with lower output current (55 mA). Neither is a drop-in replacement — check the supply voltage and output drive requirements before substituting.

Can ADA4666-2ARMZ-R7 replace ADA4666-2ARMZ?

Yes, ADA4666-2ARMZ-R7 is functionally identical to ADA4666-2ARMZ; the -R7 suffix denotes Tape & Reel packaging instead of tube. The electrical specs and package (8-MSOP) are the same.
