ALD1726GPAL

Overview

The ALD1726GPAL is a monolithic precision CMOS ultra micropower operational amplifier from Advanced Linear Devices Inc. It features rail-to-rail input and output voltage ranges, allowing operation with signals close to the supply rails. The device offers a unity gain bandwidth of 400 kHz and a slew rate of 0.17 V/µs. It operates on dual supplies from ±1V to ±5V or single supplies from +2V to +10V. Supply current is typically 20 µA at 5V. Input bias current is extremely low at 0.01 pA typical. The part is housed in an 8-pin Plastic DIP package.

Feature Summary

• Rail-to-rail input and output voltage capability for maximum dynamic range
• Ultra micropower consumption suitable for battery-operated systems
• Extremely low input bias current ideal for high source impedance applications
• Internally compensated for unity gain stability without external components

Applications

• Voltage amplifier circuits
• Photodiode amplifiers
• Charge integrators
• Precision sample and hold amplifiers
• Biochemical probe interfaces

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP package variant when sourcing. Confirm RoHS compliance status as standard versions are lead-free. Check for availability of high-temperature screening options if operating conditions exceed the commercial range. Ensure static control procedures are followed due to ESD sensitivity.

Selection Notes

Select this component for designs requiring low power dissipation combined with high input impedance. It is suitable for mixed digital/analog systems sharing a single power supply. Consider the internal switching point of the rail-to-rail input stage when designing unity gain buffers to account for offset variations. Verify load driving capabilities against capacitive requirements.

Part Context

This part belongs to the ALD1726 family of precision ultra micropower CMOS operational amplifiers. The 'G' suffix indicates enhanced robustness for rugged environments. The 'PAL' suffix specifically denotes the 8-pin Plastic Dual In-Line Package (PDIP) configuration. This family is designed for applications requiring low voltage operation and minimal power consumption.
