ALD2736ASAL

Overview

The ALD2736ASAL 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, with typical supply current of 25µA per op amp at 5V. Key electrical parameters include a unity gain bandwidth of 400KHz, slew rate of 0.17V/µs, and large signal voltage gain of 100V/mV. Input offset voltage is typically 2mV with drift of 55µV/°C. The device features rail-to-rail input and output capabilities, extremely low input bias currents of 0.01pA, and output short circuit protection. It is housed in an 8-pin SOIC package.

Feature Summary

• Rail-to-rail input and output voltage ranges enable full signal swing near supply rails.
• Ultra micropower operation provides typical 25µA supply current per amplifier for extended battery life.
• Internally compensated for unity gain stability without external frequency compensation components.
• Robust design supports operation in temperature-extreme environments and rugged conditions.

Applications

• Voltage amplifier
• Photodiode amplifier
• Data acquisition systems
• Precision Sample and Hold amplifiers
• Active filters

Procurement Notes

Verify the specific ordering suffix 'SAL' corresponds to the 8-pin Small Outline Plastic DIP (SOIC) package variant as defined in the manufacturer's ordering information. Confirm RoHS compliance status associated with the 'L' suffix if lead-free material is required for the assembly process. Ensure static control procedures are followed during handling due to ESD sensitivity.

Selection Notes

Select this component for applications requiring low power consumption alongside high input impedance and rail-to-rail signal handling. The internal offset trimming reduces the need for external nulling circuits in most configurations. Consider the 0.17V/µs slew rate and 400KHz bandwidth when designing for higher frequency signal processing tasks.

Part Context

This part belongs to the ALD2736A/ALD2736 family of precision dual ultra micropower CMOS operational amplifiers. The 'A' designation indicates specific performance characteristics compared to the standard ALD2736. The 'SAL' suffix identifies the specific plastic SOIC-8 package configuration within the broader product line that also includes DIP and CERDIP options.

Replacement Considerations

Consult the manufacturer for custom screening versions or alternative package types such as ALD2736APAL or ALD2736ADA if different form factors are required.

FAQ

Does the ALD2736ASAL require external frequency compensation?

No, the device is internally compensated for unity gain stability using a novel scheme that does not utilize a nulling resistor.

What is the typical input bias current for this operational amplifier?

The typical input bias current is 0.01pA at room temperature, resulting from reverse bias leakage currents of input protection diodes.
