¡¡¡¡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 ¨C40¡ãC to +125¡ãC temperature range.

¡¡¡¡The SGM8541/8542/8544 provide 1.1MHz bandwidth at

¡¡¡¡a low current consumption of 42?A 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 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 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.
