ALD1701BPAL

Overview

The ALD1701BPAL is a micropower rail-to-rail CMOS operational amplifier manufactured by Advanced Linear Devices Inc. It operates on single supplies from +2V to +10V or dual supplies from ±1V to ±5V, with a maximum supply current of 250µA at 5V. The device features a unity gain bandwidth of 0.7MHz and a slew rate of 0.7V/µs. Input bias current is typically 1pA (max 30pA), while input offset voltage ranges up to 10mV. It provides high open-loop voltage gain of 100V/mV and drives loads as low as 10kΩ. The component is housed in an 8-pin Plastic DIP package.

Feature Summary

• Rail-to-rail input and output voltage ranges enable full signal swing near supply rails.
• Internally compensated for unity gain stability without external frequency compensation components.
• Extremely low input bias currents suitable for high source impedance applications.
• Output short circuit protection ensures robust operation under fault conditions.

Applications

• Voltage amplifier
• Photodiode amplifier
• Data acquisition systems
• Active filters
• Picoammeter

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP package and lead-free (RoHS) compliance status before ordering. Confirm that the operating temperature range aligns with the application requirements, as this package variant supports 0°C to +70°C. Ensure static control procedures are followed during handling due to ESD sensitivity.

Selection Notes

Select the ALD1701BPAL when low power consumption and rail-to-rail performance are required in a standard DIP package. It serves as a drop-in replacement for µA741 and ICL7611 types in compatible circuits. Consider the 10mV maximum input offset voltage for precision requirements. Verify load driving capabilities against the 10kΩ minimum resistive load specification.

Part Context

This component belongs to the ALD1701 family of micropower operational amplifiers. The 'B' designation indicates specific electrical parameter tolerances compared to other variants like 'A' or 'G'. The 'PAL' suffix identifies the physical packaging as an 8-pin Plastic DIP. This series utilizes enhanced ACMOS silicon gate CMOS process technology for low power and high input impedance.

Replacement Considerations
