Output Coupling Capacitor-less Line Amplifier BD8876FV, BD8878FV Key Specifications Description Power Supply voltage: 3V to 5.5V BD8876FV, BD8878FV are output coupling THD+N: 0.003% (Typ) capacitor-less line amplifiers. These IC have a negative (V =5V, R =10k, Vo=2Vrms, 20kHz LPF) CC L voltage generator built-in and generate the negative Maximum Output Voltage: 2Vrms (Min) V =5V CC voltage from the supply voltage. It is possible to drive in a Output Noise: 10Vrms (Typ) ground reference with both voltage of the supply voltage Circuit Current (Active): 3.2mA (Typ) and the negative voltage. Therefore, these line Operating Temperature Range: -40C to +85C amplifiers have wide output range, and they can output 2Vrms(5.65V ) with the single-supply 5V. P-P Features Possible to output 2Vrms with single-supply 5V Package W(Typ) x D(Typ) x H(Max) Output Coupling Capacitor-less SSOP-B14 5.00mm x 6.40mm x 1.35mm Variable Gain+6dB / +9dB Typ.
