2 GENERAL DESCRIPTION
The BL6203 is a fully differential audio power amplifier designed for portable communication device
applications. It is capable of delivering 1.25 watt of continuous average power to an 8Ω BTL load with
less than 1% distortion (THD+N) from a 5V battery voltage. It operates from 2.2 to 5.5V.
Features like 90dB PSRR at 217Hz, improved RF-rectification immunity, the space-saving 8-bump micro
SMD package, the advanced pop & click circuitry, a minimal count of external components and
low-power shutdown mode make BL6203 ideal for wireless handsets.
The BL6203 is unity-gain stable, and the gain can be configured by external resistors.
3 APPLICATIONS
z Wireless handsets
z Portable audio devices
z PDAs, Handheld computers

Note1: stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied. Exposure to absolute maximum rated conditions
for extended periods may affect device reliability.
Note2: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and
the ambient temperature TA. The maximum allowable power dissipation is PDMAX=(TJMAX-TA)/θJA or the number
given in Absolute Maximum Ratings, whichever is lower.
