GENERAL DESCRIPTION
The MSA180 is a piezo speaker driver for OKI's speech synthesizers.
Its
voltage gain can be adjusted by a factor of up to 10.
The differential output provides an amplitude of twice the
voltage supply.
A separate output connects to the base of an external transistor for controlling system
voltage.
A standby function eliminates power loss when no input signal is present.
