DESCRIPTION
The TDA7531 is a codec for audio applica-
tion.The chip is composed by two AtoD stereo
converters, three DtoA stereo converters, a digital
programmable I&O interface, an analog volume
control, an oscillator and an analog PLL. The A to
D is a third order Sigma-Delta converter, the con-
verter resolutions is 18 bit with 93 dB of dynamic
This is preliminary information on a new product now in development. Details are subject to change without notice.
