DESCRIPTION
Patented Pop- and Click-Reduction
The TAS5414A and TAS5424A are four-channel
Technology
digital audio amplifiers designed for use in automotive
–
Soft Muting With Gain Ramp Control
head units and external amplifier modules. The
–
Common-Mode Ramping
TAS5414A and TAS5424A provide four channels at
23 W continuously into 4
Ω at less than 1% THD+N
Patented AM Interference Avoidance
from a 14.4-V supply. Each channel can also deliver
Patented Cycle-by-Cycle Current Limit
38 W into 2
Ω at 1% THD+N. The TAS5414A uses
75-dB PSRR
single-ended analog inputs, while the TAS5424A
Four-Address I2C Serial Interface for Device
employs differential inputs for increased immunity to
common-mode
system
noise.
The
digital
