Overview
The LV4992TT is the best LSI for the speaker drive for portable equipment that is battery drive, including the power amplifier circuit capable of low voltage (from 2.7V) operation and stand-by function to reduce the consumption current.

Functions and Features
• Built-in stereo SE power amplifier
   Output power 1= 160mW (VCC = 3.6V, RL = 8Ω and THD = 10%)
   Output power 2= 340mW (VCC = 5.0V, RL = 8Ω and THD = 10%)
   Output power 3= 55mW (VCC = 3.6V, RL = 32Ω and THD = 10%)
   Output power 4= 110mW (VCC = 5.0V, RL = 32Ω and THD = 10%)
• Enabling low voltage operation : VCC = from 2.7V
• Standby function : (supply current in standby mode : 0.1μA (standard) : (VCC = 3.6V)
• Thermal shut down circuit
• Enabling gain setting : Voltage gain (0 to 14dB)
• No capacitor for output phase compensation is necessary.
