Operation with 2.5V supply, it can drive 200mw into a mono 8Ω. The shutdown may be enabled by either logic high or logic low that depending on shutdown mode selection. The BTL configuration eliminates the need for external coupling capacitors on the output in most applications. The MS6901 is unity-gain stable and can be configured by external gain-setting resistors. The MS6901 has good feature for portable equipment, these features include the low voltage operation, micropower consumption shutdown mode, enhance thermal pad and small package MSOP10, make the MS6901 ideally suited for use in portable electronic equipments.

TTL compatible input. SD Mode = 0, the device entries shutdown when SD is logic low. SD Mode = 1, the device entries shutdown when SD is logic high. Bypass is the cap to the voltage divider for internal mid-supply bias. This terminal should be connected to a 0.1-μF to 10-μF capacitor CBP. The shutdown mode controls the shutdown logic level of the SD pin1.
