Data Signal Crosstalk on the Clock Part 3 -  Maxim Application Notes / 1842 / Oct-05.....[App Note]
DC/DC Converter operates from Phone Line -  15-Jan-98 Issue of EDN DC/DC converters for use inside the telephone handset require operation from the high-source-impedance phone line. Additionally, the CCITT specifications call for maximum on-hook power consumption of 25 mA. The dc/dc converter in Figure 1 is 70%-efficient at an input power of 25 mA, providing 5V at 3.4 mA. Controlled, low-peak switch..... [Design Idea by Gary Shockey, Linear Technology Corp, Milpitas, CA]
DDR Applications & PI74ssTVF16857 -  Pericom Semiconductor Application Brief # 044.....[App Note]
DDR SDRAM Memory Termination LX1672-AN-17 -  Application Note 17 from Microsem.....[App Note]
DDR2: The Next Generation Main Memory -  Pericom Semiconductor Application Note # 07)8.....[App Note]

Debugging with Combined Oscilloscope & Logic Analyzer Measurements -  Agilent Application Note.....[App Note]
Decimal to BCD Convertor -  This circuit will provide an output in Binary Coded Decimal from any of the input switches. The input switches may be expanded to 16 switches, providing a Hexadecimal to BCD conversion.
.… [Ron J.]
Decoding the HCS101 for Non-Secure Applications -  Microchip Application Note Published 29-Jul-04  (app note added 2/06)
Definition of terms, Q&As -  Application Note MiniCircuits.com  (app note added 08/08/08)
Delay Unit For Surround Sound -  The Mitsubishi M65830 Digital Delay IC has been discontinued (for reasons beyond my comprehension), and so far a suitable replacement device has not been found.  This means (of course) that you will be unable to build this delay circuit. I have left the project in place as reference, and the overall connection schematic is still valid if (when?) a replacement for the M65830 is located. The project will be updated at that time. In the meantime, just ignore the delay circuit.....(schematic / Circuit design added 9/02)
Design Considerations for a Ku-Band DRO in Digital Communication System 5/99  -  Application Note California Eastern Laboratories Doc #928.....[App Note]
Designing a Digital Compass using the PIC18f2520 -  Microchip Application Note Published 8-Aug-05  (app note added 2/06)
Designing an FCC Approved ASK RFPIC™ Transmitter -  Microchip Application Note Published 7-Jan-03  (app note added 2/06)
Designing Energy Meters with the PIC16F873a -  Microchip Application Note Published 12-Sep-05  (app note added 2/06)
Designing Low Noise Amplifiers for PCS Applications 8/25/97  -  Application Note California Eastern Laboratories Doc #923.....[App Note]
Designing Systems with the Ic/Ss Power Line Carrier Chipset -  National Semiconductor Application Note  (app note added 2/06)
Developing a CDMA Handset ASIC with Reconfigurable System Prototyping -  Agilent Application Note.....[App Note]
Devicenet™ Group 2 Slave Firmware for PIC18 with Can -  Microchip Application Note Published 6-Oct-03  (app note added 2/06)
Dialer -  (electronic circuit added 4/05)
Difference amplifier uses digital potentiometers -  30-May-02 Issue of EDN  You sometimes need to measure a small signal in the presence of a large common-mode signal. Traditional instrumentation amplifiers that use two or three op amps in their internal structure find common use in these applications. The circuit in Figure 1 presents an alternative approach that is useful when low cost and low drift are important, but when you don't need high precision..... [Design Idea by Reza Moghimi, Analog Devices, San Jose, CA]
Digi Pack Dmx 512 Lighting Controller -  (electronic circuit added 4/05)
Digisound ring modulator -  Dual Ring Modulator based on MC1496. The X and Y inputs are AC coupled and are capable of accepting 10V p-p signals. Comprises two totally independent ring modulators on the same PCB which produces the sum and difference with two input signals. Ideal for the production of a whole range of sounds including bell and gong sounds.....
Digital Analog Converters Are a Bit Analog -  Maxim Application Notes / 1055 / Sep-05.....[App Note]
Digital Audio Distribution Systems -  (app note added 5/08)
Digital Audio/ Video Switch -  8 channel switch…. [Peter Jakab, Electrical Engineer, Engineer of Informatics]
Digital Automatic Gain Control Agc -  (electronic circuit added 7/03)
