ALD2711ASAL

Overview

The ALD2711ASAL is a dual micropower precision rail-to-rail CMOS operational amplifier manufactured by Advanced Linear Devices. It operates on single supplies from +2V to +10V or dual supplies from ±1V to ±5V, with typical supply current of 200 µA at 5V. Key electrical parameters include an input offset voltage of 0.25 mV (typical), input bias current of 0.01 pA (typical), unity gain bandwidth of 0.7 MHz, and slew rate of 0.7 V/µs. The device features rail-to-rail input and output capabilities, high open-loop voltage gain, and internal offset trimming.

Feature Summary

• Rail-to-rail input and output operation allows signal voltages to reach the positive and negative supply rails without phase reversal.
• Extremely low input bias currents ensure minimal distortion of analog signals from high-impedance sources.
• Internal offset voltage trimming eliminates the need for external nulling in most applications.
• Designed for mixed digital/analog environments with robust performance in temperature-extreme conditions.

Applications

• Photodiode amplifiers
• Picoammeters
• Active filters
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'SAL' corresponds to the SOIC-8 package and lead-free (RoHS) compliance as defined in the ordering information. Confirm that the operating temperature range aligns with the SAL package specification of 0°C to +70°C. Ensure static control procedures are followed due to ESD sensitivity.

Selection Notes

Select this component when low power consumption and high input impedance are critical. The rail-to-rail capability makes it suitable for low-voltage battery-operated systems. Consider the internal offset trim feature if external nulling circuits are undesirable. Verify load requirements against the capacitive drive capability.
