ALD1736PAL

Overview

The ALD1736PAL is a precision ultra micropower CMOS operational amplifier manufactured by Advanced Linear Devices. It features rail-to-rail input and output voltage ranges, allowing operation with dual supplies from ±1V to ±5V or single supplies from +2V to +10V. The device operates with a typical supply current of 20 µA at 5V. Key electrical characteristics include a unity gain bandwidth of 400 kHz, a slew rate of 0.17 V/µs, and an extremely low input bias current of 0.01 pA. It offers high open-loop voltage gain of 100 V/mV and includes on-chip offset voltage trimming.

Feature Summary

• Rail-to-rail input and output voltage capability for maximum dynamic range in low voltage systems
• Ultra micropower consumption with typical supply current of 20 µA
• Extremely low input bias current of 0.01 pA suitable for high source impedance applications
• On-chip offset voltage trimming eliminates the need for external nulling

Applications

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

Procurement Notes

Verify that the ordering suffix 'PAL' corresponds to the 8-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm lead-free (RoHS) compliance associated with the 'L' suffix. Ensure the specific variant matches the required operating temperature range, as other suffixes denote different packages or extended temperature ratings.

Selection Notes

Select this component when designing battery-operated systems requiring minimal power dissipation and high input impedance. It is suitable for applications needing rail-to-rail signal swing without frequency compensation. Consider the 0.17 V/µs slew rate and 400 kHz bandwidth for moderate-speed signal processing tasks where low noise and low leakage are critical.

Part Context

The ALD1736 is part of the ALD1736A/ALD1736 family of monolithic CMOS operational amplifiers. It utilizes Advanced Linear Devices' enhanced EPAD silicon gate CMOS process. The device is designed for broad analog applications using low voltage dual or single battery power supplies, offering robust performance in temperature-extreme environments.

Replacement Considerations

The ALD1736A serves as the precision version of this device with tighter offset voltage specifications. Verify pin compatibility if substituting with other single op-amp packages.
