ALD1736SAL

Overview

The ALD1736SAL is a precision ultra micropower 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 typical supply current of 20 µA at 5V. Key electrical parameters include a unity gain bandwidth of 400 kHz, slew rate of 0.17 V/µs, and large signal voltage gain of 100 V/mV. Input bias current is typically 0.01 pA, and input offset voltage is 0.15 mV at ±2.5V. The device features rail-to-rail input and output capabilities, internal offset trimming, and short-circuit protection.

Feature Summary

• Rail-to-rail input and output voltage ranges for maximum dynamic range in low voltage systems
• Ultra micropower operation with extremely low input bias currents suitable for high source impedance applications
• Internal offset voltage trimming eliminates the need for external nulling circuits
• Unity gain stable without requiring external frequency compensation

Applications

• Photodiode amplifiers
• Charge integrators
• Picoammeters
• Precision sample and hold amplifiers
• Biochemical probe interfaces

Procurement Notes

Verify that the ordering suffix 'L' confirms lead-free (RoHS) compliance as specified in the manufacturer's documentation. Confirm package type matches the SOIC-8 footprint requirements for your PCB layout. Ensure operating conditions remain within the absolute maximum ratings to prevent device degradation.

Selection Notes

Select this component when designing battery-operated systems requiring minimal power consumption alongside high input impedance. The rail-to-rail capability makes it suitable for single-supply environments where signal swing must utilize the full available voltage range. Verify that the 400 kHz bandwidth meets the specific frequency response needs of the application.

Part Context

This part belongs to the ALD1736 family of monolithic CMOS operational amplifiers. The 'SAL' suffix indicates an 8-pin Small Outline Plastic DIP (SOIC) package with lead-free construction. It is designed for use in rugged environments and temperature-extreme conditions, offering robust performance compared to standard general-purpose amplifiers.

Replacement Considerations

The ALD1736ASAL is the A-grade version of this component, offering tighter specifications for input offset voltage and drift.
