UTC-IC M2073

UNISONIC TECHNOLOGIES CO., LTD
M2073
LINEAR INTEGRATED CIRCUIT
DUAL LOW VOLTAGE POWER
AMPLIFIER
„
DESCRIPTION
As a dual low voltage power amplifier, the UTC M2073 has the
internal circuits, such as parasitic oscillation preventing circuit and
muting circuit.
Considering the fixed gain of UTC M2073, there’s an additional
voltage reducing application for the UTC M2073.
The normal application of M2073 is being used as a dual audio
power amplifier in lots of portable equipments.
