ALD2736APAL

Overview

The ALD2736APAL is a precision dual ultra micropower CMOS operational amplifier manufactured by Advanced Linear Devices. It operates on single supplies from +2V to +10V or dual supplies from ±1V to ±5V. Key electrical parameters include a typical supply current of 25µA per amplifier, a unity gain bandwidth of 400kHz, and a slew rate of 0.17V/µs. The device features rail-to-rail input and output voltage ranges, extremely low input bias currents (typically 0.01pA), and high open-loop voltage gain of 100V/mV. It is housed in an 8-pin Plastic DIP package.

Feature Summary

• Rail-to-rail input and output voltage capability for maximum dynamic range
• Ultra micropower consumption with typically 25µA supply current per amplifier
• Extremely low input bias current suitable for high source impedance applications
• Internally compensated for unity gain stability without external components

Applications

• Photodiode amplifiers
• High performance portable instruments
• Precision sample and hold amplifiers
• Biochemical probe interfaces
• Active filters

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP package variant when ordering. Confirm RoHS compliance status as indicated by the 'L' suffix designation in official documentation. Ensure the application environment remains within the specified operating temperature range of 0°C to +70°C for this package type. Cross-reference the manufacturer part number directly with the datasheet to avoid confusion with other package options like SOIC or CERDIP.

Selection Notes

Select the ALD2736APAL for designs requiring low power dissipation and high input impedance. The rail-to-rail operation makes it suitable for single-supply battery systems. Consider the 0.17V/µs slew rate and 400kHz bandwidth for signal conditioning tasks. Verify that the load requirements do not exceed the specified capacitive drive limits. Ensure the input signal range stays within the absolute maximum ratings to prevent damage.

Part Context

This component belongs to the ALD2736 family of precision dual operational amplifiers. It utilizes Advanced Linear Devices' enhanced EPAD silicon gate CMOS process. The device is designed for analog applications requiring low cost and high performance in low voltage environments. It offers robust operation in temperature-extreme conditions and includes output short circuit protection.

Replacement Considerations

Direct substitutes include the ALD2736ASAL (SOIC-8) and ALD2736ADA (CERDIP-8). These variants share identical electrical characteristics but differ in physical package dimensions. Verify pin compatibility and thermal management requirements when switching between package types.
