ALD2711PAL

Overview

The ALD2711PAL is a dual micropower precision rail-to-rail CMOS operational amplifier manufactured by Advanced Linear Devices, Inc. It operates on single supplies from +2V to +10V or dual supplies from ±1V to ±5V. The device features an input common-mode range extending 300mV beyond the supply rails and output swing within 2mV of the rails under high-impedance loads. Key electrical parameters include a unity-gain bandwidth of 700kHz at ±5V, a slew rate of 0.7V/µs, and typical supply current of 200µA at 5V. Input bias current is typically 0.01pA, with large signal voltage gain up to 300V/mV. It is housed in an 8-pin Small Outline Plastic DIP (SOIC) package.

Feature Summary

• Rail-to-rail input and output operation with extended common-mode range
• Micropower consumption suitable for battery-operated systems
• Internal offset voltage trimming capability
• Output short-circuit protection

Applications

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

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin SOIC package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status as standard lead-free versions are indicated by an 'L' suffix in ordering information, though the datasheet lists 'PAL' directly. Ensure static control procedures are followed due to ESD sensitivity.

Selection Notes

Select this component for low-power analog applications requiring rail-to-rail signal handling near supply limits. The internal offset trim feature reduces the need for external nulling circuits. Consider the 700kHz bandwidth and 0.7V/µs slew rate for moderate-speed signal conditioning tasks. Verify load requirements against the 50pF capacitive drive capability.

Part Context

This part belongs to the ALD2711 family of dual monolithic CMOS operational amplifiers. Variants include ALD2711A and ALD2711B with different offset voltage specifications, and other packages such as CERDIP (DA) and Plastic DIP (SAL). The PAL designation specifically identifies the Small Outline Plastic DIP package configuration.
