产品概述 返回TOP
The CXAO42107 (single), CXAO42107A (dual) and CXAO42107B (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 +85℃ temperature range.The CXAO42107/358/324 provide 1MHz bandwidth at a low current consumption of 60μA per amplifier. Very low input bias current of 10pA enables CXAO42107/358/324 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 this series of amplifiers include safety monitoring, portable equipment, battery and power supply control, and signal conditioning and interfacing for transducers in very low power systems.The CXAO42107 is available in the Green SOT-23-5 and SC70-5 packages. The CXAO42107A comes in the Green SOIC-8, MSOP-8 and DIP-8 packages. The CXAO42107B is offered in the Green SOIC-14 and TSSOP-14 packages.
