MC34119 - Motorola

MC34119 LOW POWER AUDIO AMPLIFIER

Symbol CD FC2 FC1 Pin 1 2 3 Description Chip Disable – Digital input. A Logic “0” (<0.8 V) sets normal operation. A logic “1” (≥2.0 V) sets the power down mode. Input impedance is nominally 90 kΩ . A capacitor at this pin increases power supply rejection, and affects turn–on time. This pin can be left open if the capacitor at FC1 is sufficient. Analog ground.
