TECHNICAL DATA
KKA7050
LOW VOLTAGE MONO/STEREO POWER AMPLIFIER
GENERAL DESCRIPTION
The
KKA7050
is a low voltage audio amplifier for small radios with headphones (such as watch, pen and
pocket radios) in mono (bridge-tied load) or stereo applications.
Features
鈥?Limited to battery supply application only (typ. 3 and 4 V)
鈥?Operates with supply voltage down to 1,6 V
鈥?No external components required
鈥?Very low quiescent current
鈥?Fixed integrated gain of 26 dB, floating differential input
鈥?Flexibility in use - mono BTL as well as stereo
鈥?Small dimension of encapsulation (see package design
example)
