产品概述 返回TOP
The CXAO42123 (single), CXAO42124 (dual) and CXAO42126 (quad) are low cost, rail-to-rail input and output voltage feedback amplifiers. They have a wide input common mode voltage range and output voltage swing, and take the minimum operating supply voltage down to 2.1V. The maximum recommended supply voltage is 5.5V. All are specified over the extended -40℃ to +125℃ temperature range.The CXAO42123/4/6 provide 1.1MHz bandwidth at a low current consumption of 46μA per amplifier. Very low input bias currents of 0.5pA enable CXAO42123/4/6 to be used for integrators, photodiode amplifiers, and piezoelectric sensors. Rail-to-rail input and output are useful to designers for 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 CXAO42123 single is available in the Green SOT-23-5, SC70-5 and SOIC-8 packages. The CXAO42124 dual comes in the Green SOIC-8, MSOP-8 and TSSOP-8 packages. The quad CXAO42126 is offered in Green TSSOP-14 and SOIC-14 packages.
