ADC circuit optimizes key encoding - 02/04/99 EDN-Design Ideas
You can implement a simple and low-cost keyboard encoder by using a
key-controlled resistive divider connected to an ADC (Figure 1).....File
has multiiple circuits, scroll to this one.... [Design Idea by Vitor
Amorim, Siemens, and J Simões, University of Coimbra, Coimbra, Portugal] |

ADC controls multiple stepper-motors - 09/14/00 EDN-Design Ideas
Typical stepper-motor control circuits use either logic gates and
flip-flops or shift registers to generate the proper sequences of binary
codes.... [Design Idea by K Suresh, Indira Gandhi Centre for Atomic
Research, Kalpakkam, India] |

ADC enables temperature compensated weigh scale measurements -
5-Jul-01 Issue of EDN You can provide temperature compensation in
weigh-scale applications by simultaneously measuring both the temperature
of the bridge and the primary output of the bridge transducer..... [Design
Idea by Albert O'Grady, Analog Devices, Limerick, Ireland] |

ADC for programmable logic uses one capacitor - 12-Nov-09 Issue
of EDN Use a capacitor's charging and discharging time to sense a
user input.... [Design Idea by Jef Thoné and Robert Puers, Katholieke
Universiteit Leuven, Leuven, Belgium' Edited by Martin Rowe and Fran
Granville] |

ADC Helps Temperature Compensate Transducer - 01/20/94 EDN-Design Ideas
You can use many tricks to make temperature-compensated resistive full-bridge
transducers, such as piezoresistive pressure or strain-guage sensors. Most of
these tricks use some additional thermosensitive components that produce a
compensating voltage or current. The disadvantages of such solutions are obvious
low accuracy....[Design Idea added 11/05] [Design Idea by Alexander L Belousov,
Science Instruments Co, Baltimore, MD] |

ADC interface conditions high level signals - 30-Oct-03 Issue of EDN
Designers who build equipment for the industrial market share a widespread
problem. At one extreme, they must build equipment that supports ±10V bipolar
voltages, often riding on a high common-mode level, a requirement enforced by 30
years of legacy industrial equipment. At the other extreme, the analog signal
needs conditioning to match the full-scale range of a low-voltage,
single-supply.... [Design Idea by Moshe Gerstenhaber and Stephen Lee, Analog
Devices, Wilmington, MA] |

ADC is Surprisingly Accurate - 06/09/94 EDN-Design Ideas The
reference voltage in Fig 1a's simple rail-to-rail PWM ADC is the only critical
component. The input-voltage range extends from ground to the power rail which
also acts as the reference. The circuit is essentially a variation on the classic
dual-slope integrator,.... [Design Idea by Mike Walne, Farnell Instruments,
Wetherby, West Yorkshire, UK] |

ADC Multiplexer Expander works Transparently - 06/20/96 EDN-Design Ideas
When you need to multiplex a large number of analog signals into an ADC—as in
medical, instrumentation, and or applications—you may find it difficult to find an
appropriate ADC that has enough channels to fit your system's needs. You can add
external multiplexers, but se normally require additional control lines from
CPU. Also, time required.... [Design Idea by Mark Seiders, National
Semiconductor, Santa Clara, CA] |

ADC Shuts Down Analog Circuitry - 03/03/94 EDN-Design Ideas By
placing a variable component in the positive feedback loop of an op amp; you can
vary the gain of the stage logarithmically with respect to a linear resistance or
conductance.... [Design Idea by Emmy Denton, National Semiconductor, Santa
Clara, CA] |
