MS6890

MOSA Mono 1.1W Power Amplifier Low Voltage Operation FEATURES Operation range: 2.5V~5.5V Shutdown Current 0.1uA at 5V PSRR at 217Hz, 60dB 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 SOP8, MSOP8 and enhance thermal pad MS6890 Mono 1.1W Power Amplifier with Shutdown APPLICATIONS Portable electronic devices PDAs Communication headsets Cross-reference: LM4890, LM4893, TS4890 TPA751, MAX9716 DESCRIPTION The MS6890 is a low distortion 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 BTL configuration eliminates the need for external coupling capacitors on the output in most applications. The MS6890 is unity-gain stable and can be configured by external gain-setting resistors. The MS6890 has good feature for portable equipment, these features include the low voltage operation, micropower consumption shutdown mode, enhance thermal pad and small package SOP8, MSOP8, make the MS6890 ideally suited for use in portable electronic equipments. www.DataSheet4U.com BLOCK DIAGRAM -IN +IN 4 3 + A1 - 5 Vo1 BP SHDN VDD GND 2 1 6 7 + Bias control A2 + 8 Vo2 REV 1.0 1 www.mosanalog.com MOSA PIN CONFIGURATION Symbol /SHDN BP +IN -IN Vo1 VDD GND Vo2 Pin 1 2 3 4 5 6 7 8 MS6890 Mono 1.1W Power Amplifier with Shutdown Description /Shutdown places the entire device in shutdown mode when he...
