MOSA MS6894 Mono 1.1W Fully Differential Power Amplifier with Shutdown Selection Mono 1.1W, Fully Differential Input Excellent PSRR, Low Voltage Operation Selectable Shutdown Logic Level FEATURES ‧PSRR at 217Hz, 80dB at 5V ‧Operation range: 2.5V ~ 6.5V ‧Shutdown Current 0.1uA at 5V ‧Output power, THD+N=1% RL=8Ω, 1.1W at 5V, 0.4W at 3.3V, 200mW at 2.5V ‧Unity-gain stable ‧Space-saving MSOP10, enhance thermal pad APPLICATIONS ‧Portable electronic devices ‧PDAs ‧Communication headsets ‧Cross-reference: LM4894 DESCRIPTION The MS6894 is a fully differential power amplifier that can drive 1.1W of continuous average power into a mono 8Ω bridged-tied load (BTL). 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 MS6894 is unity-gain stable and can be configured by external gain-setting resistors. The MS6894 has good feature for portable equipment, these features include the fully differential input, low voltage operation, micropower consumption shutdown mode, enhance thermal pad and small package MSOP10, make the MS6894 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. Positive differential input The shutdown mode controls the shutdown logic level of the SD pin1. TTL compatible input Negative differential input 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.
