The two wires (SDA - serial data, SCL -<br />serial clock) carry information between the devices<br />connected to the bus. <br /><br />Therefore to obtain any feature or / and functions from the TDA8421 it needs to be controlled by a Microcomputer programmed for the functions which are needed to perform in circuit.<br /><br />have fun,<br /><br />FRANK.<br /><br />FRANK https://www.blogger.com/profile/05899055923323016216noreply@blogger.comtag:blogger.com,1999:blog-3229613061874897826.post-74250533838172923612013-09-11T01:29:06.805+02:002013-09-11T01:29:06.805+02:00Hi,
I have a TDA8421 HI-FI Audio Stereo processor ...Hi,<br />I have a TDA8421 HI-FI Audio Stereo processor from a Normende Prestige 72 and I want to make it a stereo amplifier for a boombox project, but I don't know how to set the input to external, wich is the power pin out and how to control the volume.<br />The numbers labeled above connectors correspond to the chip pin out ?<br />I'll apriciate any suggest or ideea!<br /><br />Respectfully,<br />GmoldovanuAnonymoushttps://www.blogger.com/profile/05484704091744117248noreply@blogger.com
