LV4991TT

Overview

Function and Feature

LV4991TT incorporates the power amplifier circuit operable at low voltage (2.7V or more) and has additionally the

standby function to reduce the current drain. This is the best LSI for speaker drive for the battery-driven portable

equipment, such as IC recorders, portable radios, etc. The LV4991TT is a MSOP8 (150mil) package, and The LV4991TH

of HMSOP8 (150mil) package is available.

• Monaural BTL power amplifier incorporated

• Operation at low voltage possible

• Standby function incorporated

• Second amplifier stop control function incorporated : Reducing the pop sound at startup, simple MUTE

• Overheat protection circuit incorporated

• Gain setting possible

• Output phase compensation capacitor not necessary

Standard output power = 450mW (V CC = 3.6V, R L = 8Ω, THD = 10%)

Output coupling capacitor not necessary because of differential output type

V CC = 2.7V or more

Standard current drain at standby = 0.1µA (V CC = 3.6V)

BTL voltage gain = 0 to 26dB
