General Description
The HT82V73A is an integrated class AB mono
speaker driver contained in an SOP 8-pin package.
The device is capable of delivering 1500mW of
output power into an 8Ω load with less than 10%
(THD+N) distortion from a 5V power supply. When
in the shutdown mode the very low standby current
is an important feature for a wide range of battery
powered audio applications.

PCB Layout Consideration
It is desirable to maximize the PCB cooper area connecting to GND/EPAD pin to achieve the best thermal
performance, if the board space allowed, a ground plane is highly desirable.
Absolute Maximum Ratings
Supply Voltage.......................... VSS−0.3V to VSS+6.0V
Storage Temperature........................... −50°C to 125°C
Input Voltage.............................VSS−0.3V to VDD+0.3V
Operating Temperature......................... −40°C to 85°C
Note: These are stress ratings only. Stresses exceeding the range specified under ″Absolute Maximum Ratings″
may cause substantial damage to the device. Functional operation of this device at other conditions beyond
those listed in the specification is not implied and prolonged exposure to extreme conditions may affect
device reliability.
