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

supply voltage down to 2.1V and the maximum

recommended supply voltage is 5.5 V.

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, SC70-5

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.
