Interfacing TEDS accelerometer to microcontroller with 1wire interface.

[VSS123]

Please suggest me how to interface TEDS accelerometer to signal conditioning hardware. I need 1 wire interface between TEDS accelerometer which is biased by -5V and microcontroller with 1.8V logic 1 wire interface.

Hi,

Which accelerometer are you planning to use? 

If you are using IEPE accelerometers, you could connect the output directly to some NI hardware such the the 9233, 9234 , 4461, 4462, 4471, 4472 ,4496 etc series boards

These boards will take care of the signal conditioning required. 

When you say 1 wire interface, i'm not quite sure what you are referring to..it would be helpful if you could elaborate on this.

The connection would probably seem like 1-wire but internally there would be more to take care of the signal conditioning.

hi,

thank u for your reply.

this is our circuit(attachment). our teds works with -5V bias and microcontroller  works at 1.8V and it has inbuilt 1-wire controller(in circuit i have send through attachment micro controller not shown) please suggest me how to design signal conditioning(voltage level translation with bidirectional control)
