2 ADC channels double sensor precision -  03/18/99 EDN Design Idea (contains several designs, scroll to find this one)   The accuracy of the on-chip ADCs of numerous small and inexpensive 8-bit µPs is well-suited for many applications. However, some situations benefit from just a little more accuracy from a resistive position sensor, for example. The resistive circuit in Figure 1 uses two ADC pins on a µP to double the precision of a resistive position sensor. In effect, the 8-bit ADC becomes a 9-bit ADC. The resistive part of the circuit shown in Figure 1 costs as little as $3; the cost is higher if you use a precision potentiometer as the position sensor. . . .  [by Luke J Barker, Reinke Manufacturing Co Inc, Deshler, NE]

ADC circuit optimizes key encoding -  02/02/99 EDN Design Idea (contains several designs, scroll to find this one)   You can implement a simple and low-cost keyboard encoder by using a key-controlled resistive divider connected to an ADC (Figure 1). This type of circuit is especially suitable for embedded systems that use a µC with an integrated ADC section. To obtain the best noise margin between keys, select resistors to yield an equal division of the voltage levels. To meet this criterion using the circuit in Figure 1, you must use a set of resistors with all-different, specific values.

ADC Input Driver DIFFERENTIAL to DIFFERENTIAL -  The last of our basic ADC input drivers is the differential input to differential output driver. Suppose another part of your circuit already converted a singled-ended sensor signal to ± 2Vdifferential. However, this differential signal sakes its way past noisy AC sources and switching power supplies. . . .  [design not identified]

 

ADC Input Driver DIFFERENTIAL to SINGLE-ENDED -  Your data acquisition board has an ADC that accepts a single-ended input of 0 - 5 V. However, your signal source happens to be differential. This signal may be generated from a sensor bridge where one leg swings positive while the other swings negative in response to pressure, for example. . . .  [design not identified]

 

ADC Input Driver FULLY DIFFERENTIAL AMPLIFIER -  In this series of ADC input drivers, we've created differential outputs using the obvious - two op amps, one for the positive and one for the negative output. Also, you need 8 resistors to accomplish the feat. But, wouldn't it be grand if a single device produced with both positive and negative? . . .  [design not identified]

 

ADC Input Driver SINGLE-ENDED to DIFFERENTIAL -  The continuing story of input drivers brings us to the case where your signal source is single-ended, but your ADC accepts a differential input. For example, a position sensor that swings +/-10 V gets muxed to an ADC that expects a +/-4V differential input centered around 2 V. What's the solution?. . .  [design not identified]

Analog Circuit Provides Voltage Clipping and DC Shifting for Flash ADC -  04/03/08  EDN Design Idea   A dual-current-feedback-op-amp circuit performs voltage limiting and dc shifting for a sensitive flash ADC. Many flash ADCs, such as National Semiconductor's ADC1175, have a recommended operating input-voltage range of 0. 6 to 2. 6V (Reference 1). However, in some applications, you must convert a symmetrical analog-input signal. The circuit in this Design Idea   converts a symmetrical input-voltage range of −0. 2 to +0. 2V into the recommended 0. 6 to 2. 6V range (Figure 1). The circuit also prevents the output voltage from going below −0. 3V, which would probably damage the ADC. . . .  [by Alfredo del Rio, University of Vigo, Spain]

BIOS interrupt performs A/D conversion -  03/16/00 EDN Design Idea   Most A/D-conversion techniques use dedicated hardware, usually a single-chip IC. The flexible conversion technique allows you to use successive-approximation, ramp-type, or other converters by writing the appropriate control software. The design in Figure 1 uses a PC's parallel port for interface to a DAC and a special BIOS interrupt (INT 1CH) for the conversion process. The INT CH hardware interrupt is available in all PCs. It automatically occurs 18. 2 times per second; the BIOS-timer interrupt invokes the interrupt after the interrupt updates the time-of-day count. The INT 1CH handler routine activates the hardware in Figure 1. . . .  [by J Jayapandian]

Converters Yield Droop-Free S/H Circuit -  11/17/11  EDN Design Idea  (Originally published in the January 23, 1986, issue of EDN)   In low-frequency applications, many monolithic sample/hold circuits suffer a droop rate that can cause an unacceptably large output error. The S/H circuit in Fig 1 eliminates droop error by operating two 8-bit multifunction converters back to back. The circuit requires a 5V supply and accepts analog inputs between 0 and 2. 5V (although you can scale and offset any input signal to fall within this range). . .  [by TG Barnett, The London Hospital Medical College, London, UK]

Current Input ADC Measures Voltages -  08/19/99 EDN Design Idea   A practical realization of a spread-spectrum technique lowers a µP's clock-related EMI by approximately 4 dB without the drawbacks associated with modulation (Figure 1). The spread-spectrum technique is a popular method to reduce µP-clock-related EMI (Reference 1). Using this method, the µP's clock frequency constantly shifts around and creates a moving target for quasipeak EMI detection. Although this method dramatically reduces measured EMI, it has a few drawbacks. . . .  [by Jim Todsen, Burr-Brown Corp, Tuscon, AZ]

Design Notes: Matched Resistor Networks for Precision Amplifier Applications -  10/03/13  EDN Design Note   Two-quadrant multiplying DAC utilizes octal CMOS buffer. Some ideal op amp configurations assume that the feedback resistors exhibit perfect matching. In practice, resistor non-idealities can affect various circuit parameters such as common mode rejection ratio (CMRR), harmonic distortion and stability. For instance, as shown in Figure 1, a single-ended amplifier configured to level-shift a ground-referenced signal to a common mode of 2. 5V needs a good CMRR. Assuming 34dB CMRR and no input signal, this 2. 5V level shifter exhibits an output offset of 50mV, which can even overwhelm the LSB and offset errors of 12-bit ADCs and drivers. . . .  [by Tyler Hutchison, also see Linear Technology Design Note 502]
