ALD1736ASAL

Overview

The ALD1736ASAL is a precision ultra micropower CMOS operational amplifier manufactured by Advanced Linear Devices. It operates on dual supplies of ±1V to ±5V or single supplies of +2V to +10V, with typical supply current of 20 µA at 5V. Key electrical parameters include a unity gain bandwidth of 400 kHz, a slew rate of 0.17 V/µs, and high open-loop voltage gain of 100 V/mV (100 dB). The device features rail-to-rail input and output capabilities, extremely low input bias currents of 0.01 pA, and internal offset voltage trimming. It is housed in an 8-pin Small Outline Plastic DIP (SOIC) package.

Feature Summary

• Rail-to-rail input and output voltage ranges for maximum dynamic range
• Ultra micropower operation with typically 20 µA supply current
• Internal offset voltage trimming eliminates the need for external nulling
• Robust design suitable for temperature-extreme environments

Applications

• Photodiode amplifiers
• High performance portable instruments
• Biochemical probe interfaces
• Picoammeters
• Precision sample and hold amplifiers

Procurement Notes

Verify that the ordering suffix 'SAL' corresponds to the 8-pin SOIC package variant. Confirm RoHS compliance status as indicated by the 'L' suffix. Ensure static control procedures are followed during handling due to ESD sensitivity. Check specific operating temperature range requirements against the datasheet specifications for this package type.

Selection Notes

Select this component when designing circuits requiring very low power dissipation alongside high input impedance. It is suitable for mixed digital/analog systems sharing a single power supply. Consider its rail-to-rail capability for applications needing full signal swing near supply rails. Verify that the 0.17 V/µs slew rate meets the speed requirements of the target application.

Part Context

This part belongs to the ALD1736 family of monolithic CMOS operational amplifiers. The 'A' designation indicates a specific performance grade within the series, while 'SAL' specifies the 8-pin SOIC package with lead-free construction. The device utilizes Advanced Linear Devices' enhanced EPAD silicon gate CMOS process for robust performance.

Replacement Considerations

Consult the manufacturer's official documentation for direct pin-compatible substitutes. Verify that any replacement maintains the required rail-to-rail input/output characteristics and ultra-low power consumption levels.
