With excellent linearity, this Class D amplifier improves the system power-supply rejection ratio (PSRR) and enhances performance at low frequencies.
Its high power-supply rejection ratio also prevents power-supply noise from entering the audio signal.
This enables uninterrupted accuracy over time and temperature, with high common-mode rejection ratio (CMRR) and high power-supply rejection ratio (PSRR).
The TS4601's class-leading power-supply rejection ratio of -107dB (typical) prevents noise from the handset battery from reaching the audio output.
With a power-supply rejection ratio of 57dB at 100kHz the AS1353 perfectly fulfills the noise requirements for a variety of wireless applications.
