SGM8522 Overview

150kHz 4.7μA Rail-to-Rail Input and Output CMOS Operational Amplifier 150kHz 4.7μA Micropower Operational Amplifier

Features

Product Name: 150kHz 4.7μA Rail-to-Rail Input and Output CMOS Operational Amplifier 150kHz 4.7μA Micropower Operational Amplifier

Product model: SGM8522

Product Description:

The SGM8521 (single),SGM8522 (dual) and SGM8524 (quad) are rail-to-rail input and output voltage feedback amplifiers offering low cost. They have a wide input common-mode voltage range and output voltage swing, and take the minimum operating supply voltage down to 2.1V and the maximum recommended supply voltage is 5.5V. All are specified over the extended-40°C to +125°C temperature range.

The SGM8521/2/4 provide 150kHz bandwidth at a low current consumption of 4.7μA per amplifier. Very low input bias currents of 0.5pA enable the SGM8521/2/4 to be used for integrators, photodiode amplifiers, and piezoelectric sensors. Rail-to-Rail inputs and outputs are useful to designers buffering ASIC in single-supply systems.

Applications for these amplifiers include safety monitoring, portable equipment, battery and power supply control, and signal conditioning and interfacing for transducers in very low power systems.

The SGM8521 is available in the Green SOT-23-5 and SOIC-8 packages. The SGM8522 comes in Green SOIC-8 and MSOP-8 packages. The SGM8524 is offered in Green TSSOP-14 and SOIC-14 packages
