Common-Mode Ramping
and TAS5424 provide four channels at 23 W
Patented AM Interference Avoidance
continuously into 4
at less than 1% THD+N from a
14.4-V supply. Each channel can also deliver 38 W
Patented Cycle-by-Cycle Current Limit

at 1% THD+N. The TAS5414 uses
75-dB PSRR

Four-Address I2C Serial Interface for Device
employs differential inputs for increased immunity to

common-mode system noise. The digital PWM
topology of the TAS5414 and TAS5424 provides
Configurable Channel Gains: 12-dB, 20-dB,
dramatic improvements in efficiency over traditional
26-dB, 32-dB
linear amplifier solutions. This reduces the power
