HWD2190
1 Watt Audio Power Amplifier
General Description
Key Specifications
The HWD2190 is an audio power amplifier primarily designed
for demanding applications in mobile phones and other por-
table 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.
