TDA8542AT Datasheet, PDF (2/20 Pages) NXP Semiconductors – 2 x 1.5 W BTL audio amplifier

Philips Semiconductors
2 × 1.5 W BTL audio amplifier
Product specification
TDA8542AT
FEATURES
• Flexibility in use
• Few external components
• Low saturation voltage of output stage
• Gain can be fixed with external resistors
• Standby mode controlled by CMOS compatible levels
• Low standby current
• No switch-on/switch-off plops
• High supply voltage ripple rejection
• Protected against electrostatic discharge
• Outputs short-circuit safe to ground, V_CC and across the
load
• Thermally protected.
GENERAL DESCRIPTION
The TDA8542AT is a two channel audio power amplifier
for an output power of 2 × 1.5 W with an 8 Ω load at a 6 V
supply. The circuit contains two Bridge-Tied Load (BTL)
amplifiers with a complementary PNP-NPN output stage
and standby/mute logic. The TDA8542AT comes in a
20-pin SO package.
APPLICATIONS
• Portable consumer products
• Personal computers
• Motor-driver (servo).
