ICL is tested in the circuit of Figure 1. However, in some applications IN LO will be set at a fixed known voltage power supply common for instance.

Two basic clocking arrangements can be used: Thus, it can be used as the negative supply for externally generated segment drivers such as decimal points or any other presentation the user may want icl7160 include on the LCD display. Finally, the true economy of single power supply operation ICLenables a high ick7106 panel meter to be built with the addition of only 10 passive components and a display.

See Tech Brief TB for details. However, if a negative supply is not available, it can be generated from the clock output with 2 diodes, 2 capacitors, and an inexpensive lC. However, by selecting the reference capacitor datwsheet that it is large enough in comparison to the stray capacitance, this error can be held to less than 0.

Average DC component is less than 50mV. D, D1, and E1 dimensions do not include mold flash or protrusions. A worst case condition would be a large positive common mode voltage with a near full scale negative differential input voltage.

For these critical applications datasyeet integrator output swing can be reduced to less than the recommended 2V full scale swing with little loss of accuracy. About Intersil Intersil Corporation is a leading provider of innovative power management and precision analog solutions.


Similarly, units with a negative TC may cycle between overrange and a non-overrange count as the die alternately heats and cools. It is icl71066 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.

All other trademarks mentioned are the property of their respective owners. To achieve maximum rejection of 60Hz pickup, the signal integrate cycle should be a multiple of 60Hz. This is because over-range is a low dissipation mode, with the three least significant digits blanked. On the 2V scale, a 0. This differential voltage can be within a wide common mode range: All Rights Reserved Intersil and design is a trademark owned by Intersil Corporation or one of its subsidiaries.

At the end of this phase, the polarity of the integrated signal is determined. The company’s products address some of the largest markets within the industrial and infrastructure, mobile computing and high-end consumer markets. Figures 5 and 6 show such an application. However, care must be exercised to assure the integrator output does not saturate. Of course, if different oscillator frequencies are used, these values should be changed in inverse proportion to maintain the same output swing.

Integrating Capacitor The dayasheet capacitor should be selected to give the maximum voltage swing that ensures tolerance buildup will not saturate the integrator swing approximately. An external reference is used. Input low is internally connected to analog COMMON and input high is connected across the previously charged reference capacitor. Also the icl1706 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.


Dambar protrusions shall not exceed 0. This supply is made stiff to absorb the relatively large capacitive currents when the back plane BP voltage is switched. For information regarding Intersil Corporation and its products, see www.

Operating Conditions Temperature Range. The analog input required to generate full scale output counts is: For the most updated datasheet, application notes, related documentation and related parts, please see the respective product information page found at www. Mold flash or protrusions shall not exceed 0. Devices with a positive TC reference may require several counts to pull out of an over-range condition. In all cases negligible DC voltage exists across the segments.

Pb-free PDIPs can be used for through hole wave solder processing only. For signals less than full scale, auto-zero gets the unused portion of reference de-integrate. Signal Integrate Phase During signal integrate, the auto-zero loop is opened, the internal short iicl7106 removed, and the internal input high and low are connected to the external pins. E and eA are measured with the leads constrained to be datasbeet to datum -C.

The integrator output can swing to within 0. An external oscillator connected to pin In fact, in selected applications no negative supply is required.
