LV4992TT
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.
