The CXAO42108A, CXAO42108B and CXAO42108C micro power, low voltage operational amplifiers are designed for battery-powered applications. The amplifiers operate on a supply voltage as low as 1.8V (±0.9V). High-performance, single-supply operation with rail-to-rail capability makes the CXAO42108A/-B/-C useful for a wide range of applications.In addition of small packages, the CXAO42108A/-2/-4 feature impressive bandwidth, low bias current and low noise relative to the very low quiescent current.The single CXAO42108A is available in Green SC70-5, SOT-23-5 and TDFN-2×2-6L packages. The dual CXAO42108B is available in Green SOT-23-8 and SOIC-8 packages. The quad CXAO42108C is available in Green TSSOP-14 package. They are specified over the extended -40℃ to +125℃ temperature range.
