ALD1731APAL

Overview

The ALD1731APAL is a precision CMOS operational amplifier manufactured by Advanced Linear Devices Inc. It features a micropower design with an input bias current of 10 pA and an input offset voltage of 400 µV. The device offers a gain-bandwidth product of 700 kHz and a slew rate of 0.7 V/µs. It supports a supply voltage span from 2 V to 10 V, enabling operation in low-voltage single-supply systems. The output type is rail-to-rail. The component is housed in an 8-pin DIP package for through-hole mounting.

Feature Summary

• Micropower CMOS architecture designed for critical low-current applications
• Rail-to-rail output capability for maximum dynamic range
• Low input bias current of 10 pA for high-impedance signal integrity

Applications

• Low-voltage single-supply systems
• Precision instrumentation circuits
• High-impedance sensor interfaces

Procurement Notes

Verify the lifecycle status as Not Recommended for New Designs (NRND) before procurement. Confirm that the 8-pin DIP package aligns with existing board layouts. Ensure supply voltage requirements match the 2 V to 10 V operating range. Check for alternative components if long-term availability is a constraint due to the NRND status.

Selection Notes

Select this component when ultra-low input bias current is required alongside rail-to-rail output performance. It is suitable for designs constrained by low supply voltages between 2 V and 10 V. Consider the 700 kHz bandwidth limit for high-speed applications. Verify compatibility with through-hole assembly processes given the DIP-8 package style.
