Maxim Integrated Products has used 3-dimensional (3D) chip assembly to offer its first mono, 3.2W, Class D amplifier with integrated input coupling capacitors.
Even with the integrated input capacitors, the MAX98314 fits is a 1mm x 1mm package size.
“Maxim has taken advantage of its truly innovative 3D process, opening the doors to countless possibilities for future solutions that enhance mobile devices,” said Kristy Lypen, director of business management for Maxim.
The integrated capacitors are designed to provide better voltage-independence and matching than standard Class D amplifiers with external input capacitors.
"With excellent linearity, this Class D amplifier improves the system power-supply rejection ratio (PSRR) and enhances performance at low frequencies," said the supplier.
Maxim claimed this 3.2W amplifier provides "Class AB audio performance with Class D efficiency".
