chemistries. Analog type needle output meter appears like an automobile gas gauge. __ Designed by Jim Haggerman, Hagerman Technology LLC
Analog LED Bar VU Meter - The circuit was designed to work with an audio power amplifier which operated off +18v-0v-18v power rails. The actual voltage used is not too critical except that the feedback is referred to the LED chain which itself is anchored to a +12v rail, hence the separate stabilizer __ Designed by Richard Torrens
Analog Milliamp Meter Used as Voltmeter - A milliamp meter can be used as a volt meter by adding a series resistance. The resistance needed is the full scale voltage reading divided by the full scale current of the meter movement. So, if you have a 1 milliamp meter and you want to read 0-10 volts you will need a total resistance of 10/.001 = 10K ohms. The meter movement itself will have a small resistance __ Designed by Bill Bowden
Analog multiplexers help test ISA bus IRQs & DRQs - EDN Design Ideas: 12/07/1995 There are 11 interrupt-request (iRQ) lines and seven DMA-request (DMQ) lines available on an iSA connector. These lines are iRQ3, 4, 5, 6, 7, 9, 10, 11, 12, 14, and 15 and DRQ0, 1, 2, 3, 5, 6, and 7. For diagnostic purposes, you should equip each line with its own control circuit to set each output low, high, or in tristate mode to avoid conflicts with installed add-on boards.

Analog Switch Cuts Peak-Detector Reset Time - 05/25/95 EDN Design Ideas: The schematic in Fig 1 is a basic configuration for a unity-gain peak detector using the PKD-01FP monolithic peak detector from Analog Devices. The reset time, tRES, is the time necessary to discharge the hold capacitor CH. tRES and the acquisition time tACQ are functions of the IC 's output-current capability. With CH10 nF, this output-current limitation sets both tRES and tACQ to about 220 �sec Design by Gualtiero Bolognesi, Landis & Gyr, Peschiera Borronmeo, Italy

Analog-Input serves any microcontroller - 20-Dec-01 EDN Design Ideas: The simple ADC in Figure 1 is perfect for getting analog signals into a purely digital microcontroller. Using just five surface-mount parts, you can assemble it for less than 50 cents (1000], which is approximately half the cost of a single-chip-ADC approach in the same volume. Moreover, this design takes only one pin from the microcontroller to operate Design by Steven Hageman, Agilent Technologies, Santa Rosa, CA
Analogue & Digital IC Testers - This unusual design works on the assumption that most IC failures are caused by the PN junctions at their inputs and outputs. in testing these, it does not need any circuitry or test configurability to determine the correct operation of the IC 's functions, instead simply providing indication on LEDs of the PN junction characteristics of each pin. For digital ICs the failure of an LED to light for a pin will usually indicate a failed PN junction there. Linear ICs may give more complex readings when in good condition, so a known good IC of the same model and manufacturer must first be inserted, and its reading compared to the suspect IC manually to observe any differences. __ Designed by Kevin Koster

Anemometer Fights Dust - 08/30/01 EDN Design Ideas: As higher levels of power dissipation underscore the need for cooling, andfans are finding their way into small electronic enclosures. The dust that fans pull into these enclosures can, however, cause major problems for high-reliability systems. By coating heat sinks and electrically charged components, the dust acts as a blanket that raises the effective thermal impedance betw Design by Jim Christensen, Maxim Integrated Products, Sunnyvale, CA

Anticipator Improves On Earlier Idea - EDN Design Ideas: 05/24/2012 A self-biasing thermistor circuit had an overall dominant thermal/electrical time constant as small as 25 msec but had a significantly rounded response following a square (thermal) input pulse of 100 msec; the source was a pulsed blue LED. A single-op-amp-based “anticipator-like” circuit generated a more faithful picture of the actual input excitation, and improved on the circuit described in a previous Design ideas (Reference 1). The lowpass filter in Figure 1, with an RC time constant of approximately 25 msec, models the circuit. Design by Nicholas Lockerbie, Scottish Universities Physics Alliance, Glasgow, Scotland
Anticipator Speeds Signal Settling to a Final Value - 03/17/11 EDN Design Ideas: Use a differentiator circuit to predict the final value of an exponential signal. The circuit in this Design idea anticipates, or jumps instantly to, the final voltage of an input-signal change. it relies on the fact that the intended input signal changes exponentially with a known time constant. This circuit was adapted from a 1970s-era instant-reading electronic thermometer, which displayed a patient’s body temperature within seconds after a thermometer probe was placed under the patient’s tongue. it exploits the fact that the temperature probe’s exponential thermal response-time characteristic is known. Design by Tim Regan, Linear Technology App Note, San Jose, CA
Antilog Converter Linearizes Carbon Dioxide Sensor - EDN Design Ideas: 10/13/2014 Simplify gas sensor interface with some analog preprocessing - While most carbon dioxide sensors use IR technology, electrochemical sensors are a serious competitor because of their high sensitivity, wide measurement range, and low price. As a rule, electrochemical sensors connect to a microcontroller through a buffer amplifier with an extremely low bias current (<1pA).
