New processing algorithms are always being developed. Analog
Devices also provides proprietary and third-party algorithms
for applications such as matrix decoding, bass enhancement,
and surround virtualizers. Contact Analog Devices for
information about licensing these algorithms.
Several power-saving mechanisms have been designed into the
ADAU144x, including programmable pad strength for digital
I/O pins and the ability to block the master clock from reaching
unused subsystems.
The ADAU144x is fabricated on a single monolithic integrated
circuit and is housed in a 100-lead package for operation over
the −40°C to +105°C temperature range. The ADAU1442 and
ADAU1445 are housed in a 100-lead TQFP package, with an
exposed pad to assist in heat dissipation. The ADAU1446, due to its
lower power consumption, is housed in a 100-lead LQFP package.
