DAI Interface for Playing MP3 Music -  (app note added 6/07)
Data acquisition system captures 16-bit voltage measurements using the USB -  05/25/06 EDN-Design Ideas  USB interface simplifies PC-based data capture system....[Design Idea added 9/08] EDN is migrating links. This link is not verified.  Search the "title" + "EDN" for new link.
Data acquisition system uses fault protection -  15-Apr-04 Issue of EDN  Sensitive systems, such as those in aircraft, must withstand fault conditions, thereby avoiding component and system damage, because a sensor failure could cause a catastrophic event to occur. A channel protector, comprising two n-channel MOSFETs connected in series with a p-channel MOSFET, can protect sensitive components from voltage transients in the signal path, whether or not the power sup.... [Design Idea by Catherine Redmond, Analog Devices, Limerick, Ireland]

Data Conversion Design Techniques for Process Control Applications/ AN-42003 -  Fairchild Application Notes / (app note added 6/06)
Data Transmission Lines & Their Characteristics -  National Semiconductor Application Note 05 Oct1998 / (app note added 5/02)
Data-acquisition system captures 16-bit voltage measurements using the USB -  5/25/06  EDN Design Ideas  The USB has become the interface of choice for connecting to PCs. Available on all relatively modern  PCs, the USB offers a standard connector and can supply power to peripherals  at 5V and as much as 100 mA of current. The circuit in Figure 1....PDF has several circuits, you will need to scroll to find this one.... [Design Idea by Terry Millward, Maxim Integrated Products Inc, Blonay, Switzerland]
Data-acquisition system uses fault protection 04/15/04 EDN-Design Ideas  Sensitive systems, such as those in aircraft, must withstand fault conditions, thereby avoiding component and system damage, because a sensor failure could cause a catastrophic event to occur. A channel protector, comprising two n-channel MOSFETs connected in series with a p-channel MOSFET, can protect sensitive components from voltage transients in the signal path, whether or not the power sup....

DDR SDRAM Signaling Design Notes/ MS-6500 -  Fairchild Application Notes / (app note added 6/06)
DDS IC plus frequency-to-voltage converter make low-cost DAC -  5-Feb-04 Issue of EDN  Precision DACs are essential in many consumer, industrial, and military applications, but high-resolution DACs can be costly. Frequency-to-voltage converters have good nonlinearity specifications—typically, 0.002% for the AD650—and are inherently monotonic.  This Design Idea shows how you can use a frequency-to-voltage converter and a DDS (direct-digital-synthesizer] chip for precise....
