ALD1706PAL

Overview

The ALD1706PAL is a monolithic CMOS ultra micropower operational amplifier manufactured by Advanced Linear Devices Inc. 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 Plastic DIP 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

• Voltage amplifier
• Photodiode amplifier
• Data acquisition systems
• Active filters
• Picoammeter

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP package and standard commercial operating temperature range. Confirm RoHS compliance status as indicated by the ordering information. Ensure static control procedures are followed during handling due to ESD sensitivity. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and lead times.

Selection Notes

Select this component for applications requiring high input impedance and low power dissipation in portable battery-operated systems. The rail-to-rail performance allows for maximum signal swing in low voltage environments. Consider the 0.7MHz bandwidth and 0.7V/µs slew rate for moderate speed signal processing tasks. Verify that the load requirements do not exceed the specified capacitive or resistive drive limits.

Part Context

This part belongs to the ALD1706 family of ultra micropower rail-to-rail CMOS operational amplifiers. The family includes variants such as ALD1706A, ALD1706B, and ALD1706G, which differ primarily in input offset voltage specifications. The PAL suffix specifically denotes the plastic DIP packaging option within this series.
