LINEAR INTEGRATED CIRCUIT
MONAURAL MIC AMP. FOR VIDEO CAMERA
DESCRIPTION
The UTC M2110 is a monaural microphone amplifier. It’s used for video camera which can operate from 2.7V. For the performance is small package and low operating current. So it is easy to design the downsizing and low consumption.
FEATURES
*Operating voltage: 2.7V~5.3V *Low operating current: V+=5V, 3.5mA (Typ,) V+=3.3V, 1.1mA (Typ.) *Short circuit protection for external MIC.
