分享资料个
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 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.
