ALD2711SAL

Overview

The ALD2711SAL 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. Key electrical characteristics include a unity gain bandwidth of 0.7MHz and a slew rate of 0.7V/µs at ±5V. Input bias current is typically 0.01pA with input resistance exceeding 10^13Ω. The device features output short circuit protection and can drive up to 50pF capacitive loads. Operating temperature range for the SAL package is 0°C to +70°C.

Feature Summary

• Rail-to-rail input and output voltage swing capability
• Extremely low input bias currents suitable for high impedance sources
• Internal offset voltage trimming eliminates need for external nulling
• Unity gain stable with robust design for extreme environments

Applications

• Photodiode amplifiers
• Picoammeters
• Active filters
• Data acquisition systems
• Sensor and transducer amplifiers

Procurement Notes

Verify the specific suffix 'SAL' corresponds to the 8-pin Small Outline Plastic DIP (SOIC) package with an operating temperature range of 0°C to +70°C. Confirm RoHS compliance status as standard lead-free versions are indicated by an 'L' suffix in ordering information, though this part number implies standard configuration. Ensure static control procedures are followed due to ESD sensitivity.

Selection Notes

Select the ALD2711SAL for applications requiring micropower consumption and high input impedance. It is suitable for battery-operated systems and mixed digital-analog circuits sharing a power supply. Consider the ALD2711ADA variant if operation in temperature-extreme environments (-55°C to +125°C) is required instead of the commercial grade SAL package.

Part Context

This component belongs to the ALD2711 family of dual monolithic CMOS operational amplifiers. The family includes variants like ALD2711A and ALD2711B which differ primarily in input offset voltage specifications. All variants share the same architecture, offering high open-loop voltage gain and high useful bandwidth designed for analog serial stages and flexible input signal bias levels.
