SGM8542運算放大器的實用參考書

　　The SGM8541 （single） ，SGM8542 （dual） and SGM8544

　?。╭uad） 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 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.
