24bit Audio CODEC series
3W+3W Class AB/D Speaker AMP
Stereo Audio CODEC
BU26156RFS
General Description
BU26156RFS is Low Power Stereo Audio CODECs with
built-in various acoustic effects. BU26156RFS has stereo
line and monaural mic inputs that can input to 2Vrms,
stereo speaker amplifier that can change Class AB / D
and stereo Headphone Outputs.BU26156 also has
built-in voltage regulator for the stability of CODEC
characteristic that is sensitive to the outside noise.

Do not short the output pin to another output pin, power supply pin or GND pin.
(Output pin includes an IO pin which is in output mode)
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.

When Reset pin is made Low level, internal LDO is power down mode.
It is necessary for 1ms until REGOUT pin becomes Low level. The recommendation of tW_RST is 1ms over.
