MSA180 - Piezo Speaker Amplifier

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.

Key Features

  • 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 :.

E2D0049-39-21 www.DataSheet4U.com ¡ Semiconductor ¡ Semiconductor MSA180 Piezo Speaker Amplifier This version: Feb. 1999 MSA180 Previous version: May. 1997 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. FEATURES • Power supply voltage : 2.0 V to 6.0 V (single supply voltage) • Low current consumption : 4.
