Cosine COS4890
The COS4890 is a high quality audio power amplifier for portable electronic devices. It is capable of delivering 1.2 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5.2V power supply. It does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.FEATURES

GENERAL DESCRIPTION
The COS4890 is unity-gain stable and can be configured by external gain-setting resistors. It features a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with logic low. Additionally, the COS4890 features an internal thermal shutdown protection mechanism. The COS4890 contains advanced pop & click circuitry which eliminates noises that occurs during turn-on and turn-off transitions. Pin Dragram Rev1.0 Copyright@2018 Cosine Nanoelectronics Inc.
