Product Summary

The ncp2890dmr2g is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The ncp2890dmr2g is capable of delivering 1.0 W of continuous average power to an 8.0Ω BTL load from a 5.0 V power supply, and 320 mW to a 4.0 Ω BTL load from a 2.6 V power supply. The ncp2890dmr2g provides high quality audio while requiring few external components and minimal power consumption. It features a low-power consumption shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low. Applications are (1)Portable Electronic Devices; (2)PDAs; (3)Wireless Phones.
