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