KKA7050
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
- Limited to battery supply application only (typ. 3 and 4 V)
- Operates with supply voltage down to 1,6 V
- No external ponents required
- Very low quiescent current
- Fixed integrated gain of 26 d B, floating differential input
- Flexibility in use
- mono BTL as well as stereo
- Small dimension of encapsulation (see package design example)
