Output Coupling Capacitor-less
Line Amplifier
BD8876FV, BD8878FV
Description
BD8876FV, BD8878FV are output coupling
capacitor-less line amplifiers. These IC have a negative
voltage generator built-in and generate the negative
voltage from the supply voltage. It is possible to drive in a
ground reference with both voltage of the supply voltage
and the negative voltage. Therefore, these line
amplifiers have wide output range, and they can output
2Vrms(5.65VP-P) with the single-supply 5V.
Features
 Possible to output 2Vrms with single-supply 5V
 Output Coupling Capacitor-less
 Variable Gain（+6dB / +9dB Typ.） [BD8876FV]
 Fixed Gain（+6.7dB Typ.）[BD8878FV]
 Integrated Negative Power Supply
 Ground-Referenced Outputs
 Integrated Short-Circuit and Thermal Protection
