BD88xxxGUL is output coupling capacitorless headphone amplifier. This IC has a negative voltage generator of regulated type built-in and generates the direct regulated negative voltage from the supply voltage. It is possible to drive headphones in a ground standard with both voltage of the positive voltage (+2.4V) and the negative voltage (-2.4V). Therefore .
1) 2.4V to 5.5V Single-Supply Operation 2) No Bulky DC-Blocking Capacitors Required 3) No Degradation of Low-Frequency Response Due to Output Capacitors 4) Virtual Ground-Referenced Outputs 5) Gain setting
BD88200GUL: Variable gain with external resistors BD88210GUL: -1.0V/V BD88215GUL: -1.5V/V BD88220GUL: -2.0V/V 6) Low THD+N 7) Low Supply Current 8) Integrated Negative Power Supply 9) Integrated Short-Circuit and Thermal-Overload Protection 10) Small package VCSP50L2 (2.1mm x 2.1mm)
●Applications
Mobile Phones, Smart Phones, PDAs, Portable Audio Players, PCs, TVs, Digital Cameras, Digital V.
