功能特点

产品名称:1.1MHz 42μA Rail-to-Rail Input and Output CMOS Operational Amplifier 1.1MHz 42μA 微功耗运算放大器

产品型号：SGM8544

产品描述：

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
