ALD1706GPAL

Overview

The ALD1706GPAL is a monolithic CMOS ultra micropower operational amplifier manufactured by Advanced Linear Devices. It features rail-to-rail input and output voltage ranges, making it suitable for single or dual supply systems ranging from +2V to +10V or ±1V to ±5V. The device offers a unity gain bandwidth of 0.7MHz, a slew rate of 0.7V/µs, and a typical input bias current of 1.0pA. It operates within an ambient temperature range of 0°C to +70°C and is housed in an 8-pin Small Outline Plastic DIP (SOIC) package.

Feature Summary

• Rail-to-rail input and output voltage capability
• Extremely low input bias currents with on-chip offset trimming
• Unity gain stable without external frequency compensation
• Output short circuit protection

Applications

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

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin plastic DIP package configuration required for your design. Confirm that the commercial grade operating temperature range of 0°C to +70°C meets your environmental specifications. Ensure static control procedures are followed during handling due to ESD sensitivity.

Selection Notes

Select this component when designing circuits requiring very low power dissipation alongside high input impedance. It is appropriate for applications where signal swings must approach the supply rails. Consider the 0.7MHz bandwidth and 0.7V/µs slew rate for moderate speed requirements. Verify compatibility with mixed digital/analog power supplies if used in such environments.

Part Context

This part belongs to the ALD1706 family of ultra micropower rail-to-rail CMOS operational amplifiers. The 'G' suffix typically denotes general performance specifications, while 'PAL' indicates the 8-pin plastic DIP package variant. The series is designed for battery-operated systems and rugged environments using enhanced ACMOS silicon gate process technology.

Replacement Considerations

Consult the manufacturer's documentation for direct pin-compatible alternatives within the ALD1706A, ALD1706B, or standard ALD1706 families. Verify electrical parameter overlaps before substituting.
