ALD2726SBL

Overview

The ALD2726SBL is a dual precision CMOS operational amplifier featuring integrated EPAD technology for user-programmable offset voltage adjustment. It operates on single supplies from 2V to 10V or dual supplies of ±1V to ±5V, with a typical supply current of 50µA. The device offers rail-to-rail input and output capabilities, a bandwidth of 200kHz, and a slew rate of 0.1V/µs. Input bias current is typically 0.01pA, and the initial input offset voltage is 100µV maximum. It is housed in a 14-pin SOIC package.

Feature Summary

• Integrates Electrically Programmable Analog Device (EPAD) technology for permanent, software-controlled 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 current and high open-loop gain for precision signal conditioning.
• Supports in-system programming to compensate for component tolerances and environmental drift.

Applications

• Sensor interface circuits
• Biochemical probe interfaces
• Precision sample and hold amplifiers
• Portable instruments

Procurement Notes

Verify the specific suffix 'SBL' against official documentation to confirm the package type and temperature range. Ensure compatibility with standard EPAD programmers if electrical trimming is required. Confirm that the application circuit supports the necessary programming pulses and pin configurations defined in the datasheet.

Selection Notes

Select this component when system-level calibration is required to minimize total input offset voltage errors. It is suitable for applications demanding micropower operation with programmable precision. Consider the trade-off between the limited offset program range of the non-E version and the need for factory pre-programming versus user flexibility.

Part Context

This part belongs to the ALD2726 family of dual ultra-micropower CMOS operational amplifiers. It shares core specifications with the ALD2726E but differs in its offset voltage programming range and factory pre-programming status. The SBL designation indicates a specific package and temperature variant within this product line.

FAQ

How does the EPAD technology function?

EPAD uses internal CMOS FETs as in-circuit elements for trimming offset voltage bias characteristics. Parameters are stored indefinitely within the device even after power-down.

What is the difference between ALD2726 and ALD2726E?

The ALD2726E has a wider offset voltage program range (±7mV vs ±0.7mV) and is intended for user-specific programming, while the ALD2726 has a more limited range and is for standard applications.
