TC94A48FG
Single-chip Audio Digital Signal Processor
The TC94A48FG is a single-chip audio Digital Signal
Processor, incorporating two channels AD converter and
six channels DA converter.
It can realize many applications, including sound field
control, such as hall simulation, digital filters, such as
equalizers, surround sound, base boost and more.
