The CXAR41259 is a 1.3 W mono fully differential amplifier designed to drive a speaker with at least 8Ω impedance in most applications. This device operates from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent supply current.The CXAR41259 is available in the space-saving MSOP8 package and the space saving 2mm x 2mm DFN package. Features like 85dB PSRR from 90Hz to 5kHz, improved RF-rectification immunity, and small PCB area makes the CXAR41259 ideal for wireless handsets. A fast start-up time of 4 ms with minimal pop makes the CXAR41259ideal for PDA applications.
