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
ADAU1442/ADAU1445/ADAU1446, including programmable
pad strength for digital I/O pins and the ability to block the
master clock from reaching unused subsystems.
The ADAU1442/ADAU1445/ADAU1446 are fabricated on a single
monolithic integrated circuit 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, and the ADAU1446, due to its lower
power consumption, is housed in a 100-lead LQFP package.
