ALD1722GPAL

Overview

The ALD1722GPAL is a monolithic precision low power CMOS operational amplifier from Advanced Linear Devices, Inc., housed in an 8-pin Small Outline Plastic DIP (SOIC) package. It features rail-to-rail input and output capabilities with a typical supply current of 0.8 mA at ±2.5V. The device offers an input bias current as low as 0.01 pA and an input offset voltage of 25 μV at 25°C. It operates within a temperature range of 0°C to +70°C and supports single or dual supplies up to ±5V.

Feature Summary

• Extremely low input signal power draw due to minimal input bias current and offset voltage
• Rail-to-rail input and output voltage swing capability for maximum dynamic range
• Robust high-temperature operation suitable for rugged environments
• Industry standard pinout compatible with traditional op-amp configurations

Applications

• Precision cable driver circuits
• Sensor interface and transducer biasing
• Unity gain buffer amplifiers
• Capacitive and charge integration circuits
• Biochemical probe interfaces

Procurement Notes

Verify the specific suffix 'G' indicates lead-free RoHS compliance and 'PAL' denotes the 8-pin SOIC package variant. Confirm that the operating temperature range aligns with your system requirements, as this specific package version is rated for 0°C to +70°C. Ensure static control procedures are followed during handling due to ESD sensitivity.

Selection Notes

Select this component when source loading errors must be minimized in high-impedance applications. The low input bias current makes it ideal for interfacing with sensors where signal integrity is critical. Verify that the required bandwidth and slew rate meet the signal processing needs, as these parameters vary with supply voltage and load conditions.

Part Context

This part belongs to the ALD1722/ALD1722G family of precision CMOS operational amplifiers. The 'G' suffix specifies lead-free construction, while 'PAL' identifies the plastic small outline package. This series is designed to replace traditional bipolar op-amps in low-power, high-precision applications requiring minimal input loading effects.

Replacement Considerations

Consult factory documentation for custom screening versions or leaded alternatives if RoHS compliance is not required. No direct public substitute part numbers are listed in the provided datasheet.
