Overview
The ALD2701PAL is a dual monolithic CMOS micropower operational amplifier manufactured by Advanced Linear Devices Inc. It features rail-to-rail input and output voltage ranges, allowing operation with signals equal to the supply rails. The device operates on single supplies from +2V to +10V or dual supplies from ±1V to ±5V. Key electrical parameters include a unity gain bandwidth of 0.7MHz, a slew rate of 0.7V/µs, and an extremely low typical input bias current of 1pA. It offers high open-loop voltage gain and is internally compensated for unity gain stability.
Feature Summary
- Rail-to-rail input and output voltage capability
- Extremely low input bias current of 1pA
- Internally compensated for unity gain stability
- Output short circuit protection
Applications
- Voltage follower/buffer/amplifier
- Photodiode amplifier
- Data acquisition systems
- Active filters
- Picoammeter
Procurement Notes
Verify that the specific part number suffix PAL corresponds to the 8-pin Plastic DIP package as documented in the manufacturer's ordering information. Confirm that the component meets the required operating temperature range of 0°C to +70°C for this specific package variant. Ensure static control procedures are followed during handling due to ESD sensitivity.
Selection Notes
Select this component for applications requiring low power consumption and compatibility with low voltage battery-operated systems. The rail-to-rail feature makes it suitable for mixed digital/analog circuits sharing a single supply. Consider the 1pA input bias current for high source impedance applications where leakage must be minimized.
Part Context
The ALD2701PAL belongs to the ALD2701 family of dual micro-power operational amplifiers. This series utilizes an enhanced ACMOS silicon gate process. The PAL suffix specifically denotes the 8-pin Plastic DIP package option within the broader product line that also includes SOIC and CERDIP variants.
Replacement Considerations
The datasheet notes compatibility with industry standard pin configurations found in µA741 and ICL7621 types. Designers should verify functional equivalence regarding pinout and electrical characteristics before substituting these legacy components.
