Overview
The ALD4701PBL is a quad micropower rail-to-rail CMOS operational amplifier manufactured by Advanced Linear Devices. It operates on dual supplies from ±1V to ±5V or single supplies from +2V to +10V. Key electrical specifications include a maximum supply current of 1mA for all four amplifiers at 5V, an input bias current of 1pA typical, and a unity gain bandwidth of 700kHz. The device features a slew rate of 0.7V/µs, output short circuit protection, and high open-loop voltage gain. It is housed in a 14-pin Small Outline Plastic DIP (SOIC) package with an operating temperature range of 0°C to +70°C.
Feature Summary
- Rail-to-rail input and output voltage ranges enable operation near supply rails.
- Extremely low input bias currents suitable for high source impedance applications.
- Unity gain stable with internal frequency compensation.
- Output stage includes short circuit protection.
Applications
- Voltage follower and buffer circuits
- Charge integrators
- Photodiode amplifiers
- Data acquisition systems
- Active filters
Procurement Notes
Verify the specific suffix 'L' indicates lead-free (RoHS) compliance as defined in the ordering information. Confirm the package type matches the required footprint, as the PBL designation corresponds to the 14-pin Small Outline Plastic DIP. Ensure the application environment remains within the specified 0°C to +70°C operating temperature range for this package variant.
Selection Notes
Select the ALD4701PBL when a quad amplifier configuration is required with micropower consumption and rail-to-rail signal handling capabilities. It serves as a pin-compatible alternative to LM324 and ICL7641 types for +5V single supply or ±2.5V dual supply systems. Consider its low input bias current for interfacing with high-impedance sensors or transducers where minimal loading is critical.
Part Context
The ALD4701 series comprises quad monolithic CMOS operational amplifiers designed for broad analog applications. Manufactured using an enhanced ACMOS silicon gate process, the family offers trade-offs between performance parameters like slew rate and power dissipation. The ALD4701PBL specifically denotes the standard commercial grade version in a plastic SOIC package.
Replacement Considerations
The datasheet notes compatibility with industry standard pin configurations of LM324 and ICL7641 types. Verify electrical parameter alignment, particularly regarding input offset voltage and bias current, before substituting these legacy parts.
