ALD2726PBL

Overview

The ALD2726PBL is a dual monolithic rail-to-rail precision CMOS operational amplifier featuring integrated user-programmable EPAD-based offset voltage adjustment. It operates on ±1V to ±5V dual supplies or +2V to +10V single supplies with a typical supply current of 50μA. Key electrical parameters include a bandwidth of 200KHz, slew rate of 0.1V/μs, input bias current of 0.01pA, and initial input offset voltage of 50μV (max 150μV). The device supports capacitive loading up to 25pF and offers high open-loop gain.

Feature Summary

• Integrates Electrically Programmable Analog Device (EPAD) technology for in-circuit offset voltage trimming without external components.
• Features rail-to-rail input and output voltage ranges compatible with low-voltage systems.
• Provides extremely low input bias currents and high open-loop voltage gain for precision signal conditioning.
• Allows individual programming of each amplifier's offset voltage to compensate for system-level errors.

Applications

• Sensor interface circuits
• Transducer biasing circuits
• Capacitive and charge integration circuits
• Biochemical probe interfaces
• Precision sample and hold amplifiers

Procurement Notes

Verify the specific ordering suffix corresponds to the required package type, as the base part number covers multiple variants. Confirm the operating temperature range matches the application environment, noting that standard packages are rated for 0°C to +70°C while ceramic versions support -55°C to +125°C. Ensure compatibility with the ALD E100 EPAD Programmer if electrical trimming functionality is required for the design.

Selection Notes

Select this component when ultra-low power consumption and high precision are critical requirements. The ALD2726PBL is suitable for battery-operated portable instruments where micropower operation is necessary. Choose the EPAD-enabled version if the design requires eliminating manual trimming procedures or implementing automated in-system calibration to correct for component tolerances and environmental drift.

Part Context

This device belongs to the ALD2726 family of dual ultra-micropower CMOS operational amplifiers manufactured by Advanced Linear Devices. It is the dual-channel counterpart to the single-channel ALD1726E/ALD2726 series. The family utilizes an enhanced A CMOS silicon gate process to achieve high performance at very low power levels, distinguishing it from standard general-purpose op-amps.

Replacement Considerations

Direct functional substitutes within the same EPAD-trimmable family include the ALD2726ESB and ALD2726EDB, which share identical electrical characteristics but differ in package style. Standard non-trimmable equivalents like the ALD2726PB may be considered if programmability is not required, though they lack the offset correction capabilities.
