LV4993M
Bi-CMOS IC
For Portable Audio Equipment
Monaural BTL Power Amplifier
Overview
LV4993M built-in the power amplifier circuit operable at low voltage (1.8V or more) and has additionally the standby
function to reduce the current drain. It is power amplifier IC optimal for speaker drive used in battery-driven portable
equipment and the low output power system equipment.
Application
IC recorder, Portable-TV, Radio, Portable-NAVI, LCD-monitor, Digital-photo-frame, and etc.
Function and Feature
Monaural BTL power amplifier built-in
Standard output power 1 = 1.5W (VCC = 5V, RL = 8Ω, THD = 10%)
Standard output power 2 = 0.5W (VCC = 3V, RL = 8Ω, THD = 10%)
Output coupling capacitor not necessary because of differential output type
Operation at low voltage possible (Operate with two dry battery cells)
VCC = 1.8V or more
Standby function built-in
Standard current drain at standby = 0.02μA (VCC = 5V)
Second amplifier stop control function built-in: For BTL/SE mode switching, and signal muting at BTL mode.
Overheat protection circuit built-in
Gain setting possible
BTL voltage gain = 0 to 26dB
Output phase compensation capacitor not necessary
