ICL, ICL, ICLS Datasheet
Dimensions D1 and E1 to be determined at datum plane -H. Figure 10 shows this application. Devices with a positive TC reference may require several counts to pull out of an over-range condition. The same holds true for the reference voltage. Do not operate at or near the maximum ratings listed for extended periods of datasheeh.
See the ICL datasheet for an alternative. This supply is made stiff to absorb the relatively large capacitive currents when the back plane Dahasheet voltage is switched. While other types of capacitors are adequate for this application, polypropylene capacitors give undetectable errors at reasonable cost.
All these problems are of course eliminated if an external reference dataseet used. Third, a feedback icl106 is closed around the system to charge the auto-zero capacitor CAZ to compensate for offset voltages in the buffer amplifier, integrator, and comparator.
E and eA are measured with the leads constrained to be perpendicular to datum -C. Allowable protrusion is 0.
Submit Document Feedback 16 FN You may report errors or suggestions for improving this datasheet by visiting www. This differential voltage can be within a wide common mode range: Second, the reference capacitor is charged to the reference voltage. October 24, FN All Rights Reserved Intersil and design is a trademark owned by Intersil Corporation or one of its subsidiaries.
ICL is tested in the circuit of Figure 1. For mV full scale where noise is very important, a 0. Please go to the web to make sure that you have the latest revision. Included are seven segment decoders, display drivers, a reference, and a clock. Dambar protrusions shall not exceed 0. Integrating Capacitor The integrating capacitor should be selected to give the maximum voltage swing that ensures tolerance buildup will not saturate the integrator swing approximately.
The following application notes contain very useful information on understanding and applying this part and are available from Intersil Corporation.
For signals less than full scale, auto-zero gets the unused portion of reference de-integrate. For the datasheett updated datasheet, application notes, related documentation and related parts, please see the respective product information page found at www.
Since the comparator is included in the loop, the A-Z accuracy is limited only by the noise of the system. Dimensions D1 and E1 do not include mold protrusion.

Of course, if different oscillator frequencies are used, these values should be changed in inverse proportion to maintain the same output swing. In case of conflict between English and Metric dimensions, the inch dimensions control. About Intersil Intersil Corporation is a leading provider of innovative power management and precision analog solutions.
Average DC component is less than 50mV. However, if ic7l106 negative supply is not available, it can be generated from the clock output with 2 diodes, 2 capacitors, and an inexpensive lC. Please refer to TB for details on reel specifications. Finally, the true economy of single power supply operation ICLenables a high performance panel meter to be built with the addition of only 10 passive components and a display.
If there is a large common mode voltage, the reference capacitor can gain charge increase voltage when called up to deintegrate a positive signal but lose charge decrease voltage when called up to deintegrate a datzsheet input signal. Calibration is achieved by placing the sensing transistor in ice water and adjusting the zeroing potentiometer for a This makes the system slightly quieter and also avoids a divider network on the input.
In the lamp test mode, the segments have a dataeheet DC voltage no square-wave. Figures dataseet and 6 show such an application. This difference in reference ick7106 positive or negative input voltage will give a roll-over error.

See Tech Brief TB for details. This is because over-range is a low dissipation mode, with the three least significant digits blanked. The negative input signal drives the integrator positive when most of its swing has been used up by the positive common mode voltage. Mold flash or protrusions shall not exceed 0. It is identical to the ICL except that the regulated supply and back plane drive have been eliminated and the segment drive has been increased from 2mA to 8mA, typical for instrument size common anode LED displays.
However, by selecting the reference capacitor such that it is large enough in comparison to the stray capacitance, this error can be held to less than 0. Converted inch dimensions are not necessarily exact. B1 maximum dimensions do not include dambar protrusions. The ICL, with its negligible dissipation, suffers from none of these problems.
The analog input required to generate full scale output counts is: Accordingly, the reader dqtasheet cautioned to verify that data sheets are current before placing orders. Also the linearity in going from a high dissipation count such as 20 segments on to a low dissipation count such as 8 segments on can suffer by a count or more.
However, where a large common mode voltage exists i.
