Preliminary
3W STEREO CLASS-D AUDIO
POWER AMPLIFIER WITH DC
VOLUME CONTROL
DESCRIPTION
The UTC UPA2008 is a third generation 5-V class-D amplifier
which provides precise DC volume control, lower supply current,
lower noise floor, higher efficiency, smaller packaging, and fewer
external components. Designed using a new filter-free class-D
modulation technique, the UTC UPA2008 is capable of directly
driving the speakers, without needing a low-pass output filter
consisting of two inductors and three capacitors per channel.
Eliminating this output filter saves approximately 30% in system
cost and 75% in PCB area.
The UTC UPA2008 improves the chip-level shutdown control,
1µA total supply current making the device ideal for
battery-powered applications. It also protects the chip from being
destroyed by over temperature and short current failure. To save
battery power for more essential devices when battery voltage
drops to low levels, undervoltage shutdown is designed in the UTC
UPA2008.
In applications, class-D amplifier for LCD projectors, LCD
monitors, powered speakers, the UTC UPA2008 is also suitable for
battery operated and space constrained systems.
FEATURES

DESCRIPTION
Negative differential audio input for left channel
Positive differential audio input for left channel
Places the amplifer in shutdown mode if a TTL logic low is placed on this terminal;
normal operation if a TTL logic high is placed on this terminal.
Power supply for left channel H-bridge
Positive audio output for left channel
Power ground for left channel H-bridge
Negative audio output for left channel
A capacitor connected to this terminal sets the oscillation frequency in conjunction with
ROSC. For proper operation, connect a 220pF capacitor from COSC to ground.
A resistor connected to the ROSC terminal sets the oscillation frequency in conjunction
with COSC. For proper operation, connect a 120k resistor from ROSC to ground.
Analog ground
Analog power supply
DC volume control for setting the gain on the internal amplifiers. The dc voltage range is
0 to VDD
No connection
Power supply for right channel H-bridge
Negative output for right channel
Power ground for right channel H-bridge
Positive output for right channel
Tap to voltage divider for internal mid-supply bias generator used for internal analog
reference.
Negative differential audio input for right channel
Positive differential audio input for right channel
Connect to analog ground and the power grounds must be soldered down in all
applications to properly secure device on the PCB.
