AiT Lanuched a 1.10W Class AB Differential Audio Amplifiers A2203A for Mobile Phones and Other Portable Communication Device Applications
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.
These Boomer audio power amplifiers were designed specifically to provide high-quality output power with a minimal number of external components.
The A2203A does not require output coupling capacitors or bootstrap
capacitors and therefore is ideally suited for mobile phones and other
low-voltage applications where minimal power consumption is a primary
requirement.
This device also features a low-power consumption shutdown mode and an internal thermal shutdown protection mechanism. This device contains advanced pop & click circuitry which eliminates noises that would otherwise occur during turn-on and turn-off transitions.
The A2203A is available in MSOP8 and SOP8 packages.
APPLICATION: Mobile Phones / PDAs / Portable electronic devices
