Part number lm4991
BRAND National Semiconductor [NS]
Packaging 8-wdfn
Date code 10+
Price 0.6~0.8usd
Summary audio power amplifier, 8SOIC, 2.2 V ~ 5.5 V, 1.5W, LM4991, National Semiconductor
Description as follow:
The LM4991 is a mono bridged audio power amplifier capable of delivering 3W of continuous average power into a 3Ω load with less than 10% THD when powered by a 5V power supply. To conserve power in portable applications, the LM4991’s micropower shutdown mode (ISD =0.1μA, typ) is activated when VDD is applied to the SHUT-DOWN pin. The applications of the LM4991 include Wireless and cellular handsets, PDA’s, Portable computers and Desktop computers.
Parametrics
LM4991 absolute maximum ratings: (1)Supply Voltage: 6.0V; (2)Supply Temperature: -65℃ to +150℃; (3)Input Voltage: -0.3V to VDD to +0.3V; (4)Power Dissipation: Internally Limited; (5)ESD Susceptibility: 2000V; (6)ESD Susceptibility: 200V; (7)Junction Temperature: 150℃; (8)Thermal Resistance, θJC (LD): 4.3℃/W: θJA (LD): 56℃/W; θJC (MA): 35℃/W; θJA (MA): 140℃/W.
Features
LM4991 features: (1)Available in space-saving LLP and MA packages; (2)Ultra low current shutdown mode; (3)Can drive capacitive loads up to 500pF; (4)Improved pop & click circuitry reduces noises during turn-on and turn-off transitions; (5)2.2 - 5.5V operation; (6)No output coupling capacitors, snubber networks, bootstrap capacitors or gain-setting resistors required; (7)Unity-gain stable.
