MONAURAL MIC AMP. FOR
VIDEO CAMERA
DESCRIPTION
The UTC M2110 is a monaural microphone
amplifier for video camera. It can operate from 2.7V.
The performance is low operating current and
small package. Therefore 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,)
