●Description
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 a
large-capacity output coupling capacitor becomes needless and can reduce a cost, a board area, and the height of the part.
In addition, there is not the signal decrement by the low range to happen by output coupling capacitor and output load
impedance and can output a rich low tone.
●Features
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) Ground-Referenced Outputs
5) Gain setting
BD88400GUL: Variable gain with external resistors
BD88410GUL: -1.0V/V
BD88415GUL: -1.5V/V
BD88420GUL: -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 Video Cameras,
Electronic Dictionaries, Voice Recorders, Bluetooth Head-sets, etc
