SGM8544 Overview

1.1MHz 42μA Rail-to-Rail Input and Output CMOS Operational Amplifier 1.1MHz 42μA Micropower Operational Amplifier

Features

Product Name:1.1MHz 42μA Rail-to-Rail Input and Output CMOS Operational Amplifier

Product model: SGM8544

Product Description:

The SGM8541(single), SGM8542(dual) and SGM8544 (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 SGM8541/2/4 provide 1.1MHz bandwidth at a low current consumption of 42μA per amplifier. Very low input bias currents of 0.5pA enable SGM8541/2/4 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 SGM8541 is available in the tiny SOT-23-5, SC70-5 and SOIC-8 packages. The SGM8542 comes in the miniature SOIC-8 and MSOP-8 packages. The SGM8544 is offered in TSSOP-14 and SOIC-14 packages

PRODUCT DESCRIPTION

The SGM8541 (single)

，

SGM8542 (dual) and SGM8544

(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 5.5 V.

All are specified

over the extended –40°C to +125°C temperature range.

The SGM8541/8542/8544 provide 1.1MHz bandwidth at

a low current consumption of 42µA per amplifier. Very

low input bias currents of 0.5pA, enable SGM8541/8542

/8544 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 this amplifiers include safety monitor-

ing, portable equipment, battery and power supply

control, and signal conditioning and interfacing for

transducers in very low power systems.

The SGM8541 is available in the tiny SOT23-5 and SO-8

packages. The SGM8542 comes in the miniature SO-8

and MSOP-8 packages. The SGM8544 is offered in

TSSOP-16 and SO-16 packages.
