MSA180

Piezo Speaker Amplifier

This version: FeMb.S1A991980

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

• Standby current

: 4.2 mA typ (VCC=3 V, no load)

: <1 mA

• Differential output

: Twice the supply voltage (maximum output

amplitube)

• Package options :

8-pin plastic DIP (DIP8-P-300-2.54) (Product name: MSA180RS)

8-pin plastic SOP (SOP8-P-250-1.27-K) (Product name: MSA180MS-K)
