Audio driver for cellular phones
BH7823AFVM
Description
BH7823AFVM is an audio driver IC developed for
mobile audio appliances such as cellular phones.
This driver has achieved low voltage driving and
low power consumption. Audio signal can be
generated from any various audio appliances.
(This speaker can drive the load of 4 , 8 , and
12 .) Achieve high output power supply by
applying BTL. Suspend contol can keep the circuit
current at 0µA (Typ.) when it is not in use.
