ALD2711APAL

Overview

The ALD2711APAL is a dual micropower precision rail-to-rail CMOS operational amplifier in an 8-pin plastic DIP package. It operates on single supplies from +2V to +10V or dual supplies from ±1V to ±5V, with typical supply current of 200µA at 5V. Key electrical parameters include a unity gain bandwidth of 0.7MHz and a slew rate of 0.7V/µs at ±5V. Input offset voltage ranges from 0.5mV to 1.4mV, while input bias current is typically 0.01pA. The device features linear mode operation with inputs extending 300mV beyond supply rails and output swing within 2mV of rails.

Feature Summary

• Rail-to-rail input and output capability with linear operation extending 300mV beyond supply voltages
• Micropower consumption with extremely low input bias currents for minimal signal distortion
• On-chip offset voltage trimming eliminates the need for external nulling in most applications
• Robust design suitable for temperature-extreme environments and rugged conditions

Applications

• Photodiode amplifiers and picoammeters
• High performance portable instruments
• Data acquisition systems
• Active filters and sample/hold amplifiers
• Sensor and transducer amplifiers

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the lead-free (RoHS) 8-pin Plastic DIP package. Confirm the operating temperature range matches the application requirements, as this package variant is rated for 0°C to +70°C. Ensure static control procedures are followed during handling due to ESD sensitivity. Cross-reference the datasheet version to confirm electrical characteristics align with current manufacturing standards.

Selection Notes

Select the ALD2711APAL when high input impedance and low bias current are critical for precision analog signal conditioning. The device is optimized for low-voltage battery-operated systems requiring rail-to-rail signal swings. Consider the internal offset trimming feature if minimizing external components is a priority. Verify that the 0.7MHz bandwidth and 0.7V/µs slew rate meet the dynamic signal requirements of the target circuit.

Part Context

The ALD2711 series includes variants such as ALD2711ASAL (SOIC), ALD2711ADA (CERDIP), and their A/B subtypes. The ALD2711APAL specifically denotes the standard grade device in the PDIP-8 package. Other family members may offer extended temperature ranges or tighter offset specifications. The series utilizes Advanced Linear Devices' enhanced ACMOS silicon gate process for improved stability and performance.

Replacement Considerations

Direct pin-compatible substitutes within the same package and specification profile should be verified against the official cross-reference list. Alternative devices must match the rail-to-rail input/output capability and low supply current requirements. Ensure any replacement maintains the 0.7MHz bandwidth and supports the required supply voltage range.
