DESCRIPTION
The
A2203A is an audio power amplifier primarily
designed for demanding applications in mobile
phones and other portable communication device
applications. It is capable of delivering 1 watt of
continuous average power to an 8Ω BTL load with
less than 1 distortion (THD+N) from a 5V DC power
supply. Boomer audio power amplifiers were
designed specifically to provide high quality output
power with a minimal amount of external components.
The A2203A does not require output coupling
capacitors or bootstrap capacitors, a nd therefore is
ideally suited for mobile phone and other low voltage
applications where minimal power consumption is a
primary requirement.
The
A2203A features a low power consumption
shutdown mode, which is achieved by driving the
shutdown pin with logic low. Additionally, the A2203A
features an internal thermal shutdown protection
mechanism. The A2203A contains advanced pop &
click circuitry which eliminates noises which would
otherwise occur during turn on and turn off
transitions. The A2203A is unity g ain stable and can
be configured by external gain setting resistors.
The
A2203A is available in MSOP8 and SOP8
packages
