| The CP2298 is a fully differential audio power amplifier designed for demanding audio applications. It is capable of delivering 1 watt of continuous average power to an 8¦¸ BTL load with less than 1% distortion (THD+N) from a 5V battery voltage. It operates from 2.2V to 5.5V.Features like -88dB PSRR at 217Hz, improved RF-rectification immunity, the space-saving CSP9 and MSOP10 package, the advanced pop & click circuitry, a minimal count of external components and low-power shutdown mode make the CP2298 ideal for wireless handsets.The CP2298 is unity-gain stable, and the gain can be configured by external resistors. |
