SGM321YC5/TR

The SGM321(single), SGM358(dual) and SGM324(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 +85°C temperature range. The SGM321/358/324 provide 1MHz bandwidth at a low current consumption of 60µA per amplifier. Very low input bias currents of 10pA enable SGM321/358/324 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 the series amplifiers include safety monitoring, portable equipment, battery and power supply control, and signal conditioning and interfacing for transducers in very low power systems. The SGM321 is available in SOT23-5 and SC70-5 packages. The SGM358 comes in SO-8, MSOP-8 and DIP-8 packages. The SGM324 is offered in SO-14 and TSSOP-14 packages.
