ALD1706BSAL

Overview

The ALD1706BSAL is a monolithic CMOS ultra micropower operational amplifier featuring rail-to-rail input and output capabilities. It operates on dual supplies from ±1V to ±5V or single supplies from +2V to +10V. Key electrical specifications 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 offers high open-loop voltage gain of typically 100 V/mV and extremely low input bias currents with a maximum of 30 pA at 25°C. It is housed in an 8-pin SOIC package.

Feature Summary

• Rail-to-rail input and output voltage ranges for flexible signal handling near supply rails
• Extremely low input bias current suitable for high source impedance applications
• Internally compensated for unity gain stability without external components
• Output short circuit protection included

Applications

• Photodiode amplifiers
• Charge integrators
• Picoammeters
• High performance portable instruments
• Active filters

Procurement Notes

Verify the specific suffix 'SAL' corresponds to the 8-pin Small Outline Plastic DIP (SOIC) package variant. Confirm RoHS compliance status as indicated by the ordering information. Ensure the operating temperature range requirements match the commercial grade specification of 0°C to +70°C for this package type.

Selection Notes

Select this component when designing circuits requiring very low power dissipation alongside high input impedance. The rail-to-rail feature makes it suitable for single-supply battery-operated systems where maximizing dynamic range is critical. Consider the 0.7 MHz bandwidth for moderate-speed signal conditioning tasks.

Part Context

This part belongs to the ALD1706 family of ultra micropower operational amplifiers manufactured using ACMOS silicon gate CMOS process. The family includes variants like ALD1706A and ALD1706G, differentiated primarily by offset voltage and drift specifications. The ALD1706B represents a specific performance tier within this series optimized for general-purpose analog applications.

Replacement Considerations

Direct substitutes include other parts from the ALD1706 family such as ALD1706ASAL or ALD1706GSAL, provided their offset voltage and drift specifications meet the design requirements. Verify pin compatibility and package dimensions before substitution.
