Maxim claims Class D amps will simplify audio design
Maxim Integrated has introduced a couple of digital-input Class D power amplifiers that it claims will simplify audio designs by eliminating complicated programming.
“Audio design can be simplified because internal circuitry in the MAX98355/MAX98356 detects the input clock and automatically calculates the sample rate.
According to the supplier, this reduces complicated programming and the need for system software support.
“These digital-input Class D amplifiers make system design nearly plug and play,” said Robert Nicoletti, applications manager at Maxim Integrated.
The MAX98355 (pulse-code modulation, PCM) and MAX98356 (pulse-density modulation, PDM) offer high jitter tolerance with low 0.013% THD+N at 1kHz and 99dB dynamic range.
Power efficiency is 92% at RL = 8?, POUT = 900mW, VDD = 3.7V.
The chips are available in a 9-pin WLP package (1.345mm x 1.435mm x 0.64mm).
