In addition, the voltage reference input can be.
For example, if the. See the Zero Error description in this data sheet. Zero error is the difference.
In absolute conversion applicatIons, both the initial. In ratiometric converter applications. If the minimum analog input voltage value, V lN MlNis not ground, a zero offset can be done.
The data from the previous conversion remain in this latch. The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input- voltage value.
For larger clock line loading, a CMOS or low power. Note that spans smaller than 2. This WR and INTR node should be momentarily forced to logic low following a power- up cycle to insure circuit operation. V REF The full scale adjustment can be made by applying a. However, if an all zero code is desired for an analog input other than 0V, or if a narrow full scale span exists for example: In general, the reference voltage will require an initial adjustment.
IC voltage regulators may be used for references if the ambient temperature changes are not excessive. For example, if the span is reduced to 2. See Figure 17 for details.
IC voltage regulators may be used for references if the. Users should follow proper IC Handling Procedures.
These devices are sensitive to electrostatic discharge. The separate AGND point should always be wired to the. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt.
In general, the reference voltage will require an initial. Both are ground referenced. To achieve an datashedt 0V to 5V input voltage range will therefore require a minimum supply volt- age of 4.
Output Short Circuit Current. However, if an all zero code is desired for an analog input other than 0V, or if a narrow full scale span.
The converter can be operated in a pseudo-ratiometric mode. The converter can be made to output. DGND, being careful to avoid ground loops. In reduced span applica. An arbitrarily wide pulse width will hold the converter in a reset mode and the start of conversion is initiated by the low to high transition of the WR pulse see Timing Diagrams. As long as the analog V IN does not exceed the supply voltage by more than 50mV, the output code will be correct. The differential analog voltage input has good common.
These converters appear to the. In this application, the CS input is grounded and the WR.
