ALD1706SAL

Overview

The ALD1706SAL is a monolithic CMOS ultra micropower operational amplifier in an 8-pin SOIC package. It operates on single supplies from +2V to +10V or dual supplies from ±1V to ±5V. Key electrical parameters include a maximum supply current of 40 µA at 5V, a unity gain bandwidth of 0.7 MHz, and a slew rate of 0.7 V/µs. The device features rail-to-rail input and output voltage ranges, high open-loop voltage gain of 100 V/mV, and extremely low input bias current with a typical value of 0.1 pA.

Feature Summary

• Rail-to-rail input and output voltage capability for extended dynamic range
• Ultra micropower operation with minimal supply current consumption
• Extremely low input bias current suitable for high source impedance applications
• Internally compensated for unity gain stability without external components

Applications

• Photodiode amplifiers
• Picoammeters
• High performance portable instruments
• Active filters
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'SAL' corresponds to the 8-pin Small Outline Plastic Dip (SOIC) package variant. Confirm RoHS compliance status as the datasheet indicates lead-free options exist but requires factory verification for specific environmental certifications. Ensure the ordering code matches the required temperature grade and packaging format.

Selection Notes

Select this component for designs requiring very low power dissipation and high input impedance. It is suitable for battery-operated systems where supply voltages range from +2V to +10V. Consider the rail-to-rail feature if signal swings must approach supply rails. Verify that the 0.7 MHz bandwidth meets the application's frequency requirements.

Part Context

The ALD1706 series includes variants such as ALD1706A, ALD1706B, ALD1706, and ALD1706G, differentiated by offset voltage specifications. The ALD1706SAL specifically denotes the standard commercial grade version housed in an 8-pin SOIC package. This family utilizes Advanced Linear Devices' enhanced ACMOS silicon gate process technology.

Replacement Considerations

Direct substitutes within the same pinout and specification profile are not explicitly listed in the provided documentation. Users should verify compatibility with other ALD1706 variants based on offset voltage requirements.

FAQ

Does the ALD1706 require external frequency compensation?

No, the device is internally compensated for unity gain stability and does not require external frequency compensation components.

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

The typical input bias current is 0.1 pA, with a maximum specified value of 30 pA at room temperature.
