LV4993M

www.DataSheet.co.kr Ordering number : ENA1962 Bi-CMOS IC LV4993M Overview For Portable Audio Equipment Monaural BTL Power Amplifier 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 Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, industrial equipment etc.)....
