MSA180 amplifier equivalent, piezo speaker amplifier.
* Power supply voltage : 2.0 V to 6.0 V (single supply voltage)
* Low current consumption : 4.2 mA typ (VCC=3 V, no load)
* Standby current : <1 mA
* Diff.
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 exte.
