ALD2736SAL

Overview

The ALD2736SAL is a precision dual ultra micropower 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 typical supply current of 25µA per op amp at 5V. Key electrical parameters include a unity gain bandwidth of 400KHz, slew rate of 0.17V/µs, and large signal voltage gain of 100V/mV. Input offset voltage is typically 2mV, with input bias current as low as 0.01pA. The device features rail-to-rail input and output capabilities and is housed in an 8-pin SOIC package.

Feature Summary

• Rail-to-rail input and output voltage ranges allow signals to approach supply rails.
• Internally compensated for unity gain stability without external components.
• Extremely low input bias currents suitable for high source impedance applications.
• On-chip offset voltage trimming eliminates the need for nulling in most applications.

Applications

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

Procurement Notes

Verify the specific suffix 'SAL' corresponds to the lead-free (RoHS) compliant version in the 8-pin Small Outline Plastic DIP (SOIC) package. Confirm that the operating temperature range aligns with your system requirements, as this specific package variant supports 0°C to +70°C. Ensure static control procedures are followed during handling due to ESD sensitivity.

Selection Notes

Select the ALD2736SAL when designing circuits requiring low power dissipation and high input impedance. It is appropriate for battery-operated systems using single or dual supplies. Consider its rail-to-rail capability for maximizing dynamic range in low voltage environments. Verify load driving requirements against the specified capacitive and resistive limits.

Part Context

This component belongs to the ALD2736A/ALD2736 family of precision dual operational amplifiers. It utilizes Advanced Linear Devices' enhanced EPAD silicon gate CMOS process. The device is designed for broad analog applications where micropower consumption and high performance are critical constraints.

Replacement Considerations

The ALD2736ASAL is the non-RoHS equivalent within the same package type. For leaded versions, contact the factory directly as they are not standardly listed in general ordering information.
