TDA8542TS
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, VCC and across the
load
• Thermally protected.
GENERAL DESCRIPTION
The TDA8542TS is a two channel audio power amplifier
for an output power of 2 × 0.7 W with a 16 Ω load at a 5 V
supply. At a low supply voltage of 3.3 V an output power of
0.6 W with an 8 Ω load can be obtained. The circuit
contains two Bridge-Tied Load (BTL) amplifiers with a
complementary PNP-NPN output stage and standby/mute
logic. The TDA8542TS is available in a SSOP20 package.
APPLICATIONS
• Portable consumer products
• Personal computers
• Motor-driver (servo).
