ALD1706GSAL

Overview

The ALD1706GSAL is a monolithic CMOS ultra micropower operational amplifier manufactured by Advanced Linear Devices. It features rail-to-rail input and output voltage ranges, allowing operation with signals close to the supply rails. The device operates on dual supplies from ±1V to ±5V or single supplies from +2V to +10V. Key electrical parameters include a maximum supply current of 40 µA at 5V, a typical input bias current of 0.1 pA, and an offset voltage of up to 10 mV. It provides a unity gain bandwidth of 0.7 MHz and a slew rate of 0.7 V/µs. The component is housed in an 8-pin SOIC package.

Feature Summary

• Rail-to-rail input and output voltage capability for flexible signal handling
• Ultra micropower consumption suitable for battery-operated systems
• Extremely low input bias current ideal for high source impedance applications
• Internally compensated for unity gain stability without external components

Applications

• Voltage amplifier circuits
• Photodiode amplifiers
• Data acquisition systems
• Active filters
• Picoammeters

Procurement Notes

Verify that the specific part number ALD1706GSAL corresponds to the industrial temperature range (0°C to +70°C) and the SOIC-8 package configuration. Confirm RoHS compliance status as indicated by the 'L' suffix in ordering information. Ensure design accounts for ESD sensitivity during handling and installation procedures.

Selection Notes

Select this component for applications requiring low power dissipation and high input impedance. It is suitable for mixed digital/analog environments sharing a single power supply. Consider the internal switching point near the positive rail when designing unity gain buffers to account for potential offset variations.
