ADA4091-2ACPZ-R2

Overview

The ADA4091-2ACPZ-R2 is a dual-channel micropower operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply from 3.0 V to 30 V or dual supplies of ±1.5 V to ±15 V. Key electrical specifications include a maximum offset voltage of 250 µV, a gain bandwidth product of 1.27 MHz, and a slew rate of 0.46 V/µs. The device incorporates overvoltage protection (OVP) allowing inputs to exceed supply rails safely without phase reversal. It is housed in an 8-lead LFCSP package and functions within an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Features integrated overvoltage protection circuitry that allows input voltages to exceed supply rails safely without causing phase reversal or latch-up.
• Provides rail-to-rail input and output swing capability, enabling operation across the full supply voltage range for high signal-to-noise ratios.
• Delivers micropower performance with low supply current consumption per amplifier channel while maintaining precision characteristics.

Applications

• Industrial process control systems
• Battery-powered instrumentation
• Power supply control and protection circuits
• Remote sensors and transducer interfaces

Procurement Notes

Verify component authenticity through authorized distributors as the part may be subject to limited availability. Confirm the specific ACPZ suffix corresponds to the 8-lead LFCSP package variant required for your design. Ensure compliance with moisture sensitivity levels during storage and soldering processes. Cross-reference the datasheet revision to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when designing single-supply systems requiring wide input common-mode ranges and rail-to-rail output swings. It is suitable for applications demanding low power consumption alongside precision amplification. Consider the OVP feature for environments where input signals may transiently exceed supply limits. Evaluate thermal resistance values if operating at the upper end of the temperature range.

Part Context

This device belongs to the ADA4091 family of low-power, 36 V operational amplifiers manufactured by Analog Devices. It serves as the dual-channel counterpart to the quad-channel ADA4091-4. The family is designed for portable telecommunications equipment and interface applications involving Hall effect, piezoelectric, and resistive transducers.
