GENERAL DESCRIPTION
The COS4812 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 high. Additionally, the COS4812 features an internal thermal shutdown protection mechanism. It also contains a pop & click reduction circuitry which eliminates noises that occurs during turn-on and turn-off transitions. The COS4812 is available in a Green MSOP-10 package. It operates over an ambient temperature range of -40°C to +85°C.
