TS34119

TS34119 Low Power Audio Amplifier www.DataSheet4U.com Supply Voltage Range 2 V to 16V Gain Adjustable Range 0dB ~ 46dB Output Power 400mW @Vcc=12V, RL=100Ω General Description The TS34119 is a low power audio amplifier, it integrated circuit intended (primarily) for telephone applications， such as in speakerphones. It provides differential speaker outputs to maximize output swing at low supply voltages (2.0V minimum). Coupling capacitors to the speaker are not required. Open loop gain is 80dB, and the closed loop gain is set with two external resistors. A chip Disable pin permits powering down and/or muting the input signal. The TS34119 is offered in SOP-8 and DIP-8 package. Features — — — — — — — — Wide operating supply voltage (2~16V) Chip disable input to power down the IC Low quiescent current for battery powered application Lower power down quiescent current Drives a wide range of speaker load (8~100Ω) Output power exceed 250mW with 32Ωspeaker Low total harmonic distortion Gain adjustable for voice band Requires few external components Ordering Information Part No. TS34119CD TS34119CS TS34119CA -20 ~ +70 oC Operating Temp.
