DESCRIPTION
The UTC Coupling capacitor to the speaker is not required. Open loop gain is 80dB, and the closed loop gain is set with two external resistors. A chips disable pin permits powering down and/or muting the input signal. SOP-8 DIP-8 FEATURES
*Wide operating supply voltage: Vcc=2V~16V *Low quiescent supply current (Icc=2.7mA, typ) *Medium output power (Po=250mW at Vcc=6V, RL=32ohm, THD=10%) *Load impedance range (8 to 100ohm) *Low distortion *Mute function (Icc=65µA, typ) *Minimum number of external parts required TSSOP-8 *Pb-free plating product number: MC3419L BLOCK DIAGRAM UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R107-042,A UTC MC3419 LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS
