LM4951SD
Wide Voltage Range 1.8 Watt Audio Power Amplifier
LM4951
Wide V oltage Range 1.8 Watt Audio Amplifier
General Description

The LM4951isan audio power amplifier primarily designed
for demanding applicationsin Portable Handheld devices.It capableof delivering 1.8W mono BTLtoan 8Ω load,
continuous average power, with less than 1% distortion
(THD+N) froma 7.5VDC power supply.
Boomer audio power amplifiers were designed specificallyto
provide high quality output power witha minimal amountof
external components. The LM4951 does not require boot-
strap capacitors,or snubber circuits.
The LM4951 featuresa low-power consumption active-low
shutdown mode. Additionally,the LM4951 featuresan inter-
nal thermal shutdown protection mechanism.
The LM4951 contains advanced pop& click circuitry that
eliminates noises which would otherwise occur during
turn-on and turn-off transitions.
The LM4951is unity-gain stable and canbe configuredby
external gain-setting resistors.
Key Specifications
Wide Voltage Range 2.7Vto9V Quiescent Power Supply Current
(VDD= 7.5V) 2.5mA (typ) Power Output BTLat 7.5V, THD 1.8W (typ) Shutdown Current 0.01µA (typ) Fast Turnon Time 25mS (typ)
Features
Pop& click circuitry eliminates noise during turn-on and
turn-off transitions Low current, active-low shutdown mode Low quiescent current Thermal shutdown protection Unity-gain stable External gain configuration capability
Applications
Portable Handheld Devicesupto9V Cell Phone PDA
Typical Application

200942F4
*RCis neededfor over/under voltage protection.If inputs are less than VDD +0.3V and greater than –0.3V, andif inputs are
disabled whenin shutdown mode, thenRC maybe shorted.
