ALD1701GPAL

Overview

The ALD1701GPAL is a micropower rail-to-rail CMOS operational amplifier manufactured by Advanced Linear Devices. It operates on single supplies from +2V to +10V or dual supplies from ±1V to ±5V, with a maximum supply current of 300µA at 5V. The device features a unity gain bandwidth of 700kHz and a slew rate of 0.7V/µs. Input bias current is typically 1pA with a maximum of 30pA. It provides high open-loop voltage gain of 100V/mV and includes output short-circuit protection. The component is housed in an 8-pin SOIC package.

Feature Summary

• Rail-to-rail input and output voltage ranges for full signal swing capability

• Data acquisition systems

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP package as indicated in the ordering information table. Confirm RoHS compliance status if lead-free requirements are mandatory, noting that the datasheet indicates contact the factory for specific leaded or non-RoHS versions. Ensure the operating temperature range aligns with the 0°C to +70°C specification for this package type.

Selection Notes

Select this component when designing low-power analog circuits requiring rail-to-rail performance on single or dual supplies. It is appropriate for battery-operated systems due to its micropower characteristics. Consider the 700kHz bandwidth and 0.7V/µs slew rate for moderate-speed signal processing tasks. Verify that the load requirements do not exceed the specified capacitive and resistive drive capabilities.

Part Context

The ALD1701 series includes variants such as ALD1701A, ALD1701B, ALD1701, and ALD1701G, differentiated primarily by offset voltage specifications. The ALD1701GPAL specifically denotes the standard gain version packaged in an 8-pin Plastic DIP. This family utilizes enhanced ACMOS silicon gate process technology to achieve high input impedance and low power consumption simultaneously.

Replacement Considerations

The datasheet notes compatibility with industry standard pin configurations found in µA741 and ICL7611 types. Designers should verify electrical parameter overlaps before substituting these legacy parts.
