ALD4701BPBL

Overview

The ALD4701BPBL 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, with total supply current of 1mA maximum at 5V. The device features 1pA typical input bias current, 100V/mV open-loop voltage gain, and 0.7V/µs slew rate. It is housed in a 14-pin Small Outline Plastic DIP (SOIC) package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Rail-to-rail input and output voltage ranges for flexible signal handling
• Extremely low input bias currents suitable for high source impedance applications
• Unity gain stable with internal frequency compensation
• Output short circuit protection

Applications

• Voltage follower/buffer/amplifier
• Charge integrator
• Photodiode amplifier
• Data acquisition systems
• Active filters

Procurement Notes

Verify the specific suffix 'PBL' corresponds to the 14-pin SOIC plastic package and commercial temperature grade (0°C to +70°C). Confirm RoHS compliance status as indicated by the 'L' suffix. Ensure the ordering code matches the exact manufacturer part number to avoid confusion with ceramic or extended temperature variants.

Selection Notes

Select this component when low power consumption and rail-to-rail performance are required in single or dual supply systems. It serves as a drop-in replacement for LM324 and ICL7641 types while offering superior input bias current characteristics. Consider its micropower nature for battery-operated portable instruments and sensor interfaces.
