3W, Mono, Filterless, Class-D Audio Power Amplifier |
| OVERVIEW |
| The CP2210 is a high efficiency, mono, filterless, Class D audio power amplifier designed for demanding audio applications. It is capable of delivering 3W of continuous average power to a 4¦¸BTL load with less than 10% distortion (THD+N) from a 5V battery voltage. It operates from 2.5V to 5.5V.Features like 90% efficiency, -80dB PSRR at 217Hz, improved RF-rectification immunity, the space-saving CSP9 and DFN8 packages, the advanced pop & click circuitry, a minimal count of external components and low-power shutdown mode make the CP2210 ideal for wireless handsets.The gain of the CP2210 can be configured by external input resistors, which allows independent gain control from multiple sources by summing the signals. Short circuit and thermal protection prevent the device from damage during fault conditions. |
