V REF The full scale adjustment can be made by applying a. As long as the analog V IN does not exceed the supply voltage by more than 50mV, the output code will be correct. For example, if the. The output data latch is not updated if the conversion in progress is not completed. Datazheet the minimum analog input voltage value, V lN MlNis not ground, a zero offset can be done.
The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input- voltage value. In ratiometric converter applications.

In this application, the CS input is grounded and the WR. In reduced span applica. These devices are sensitive to electrostatic discharge. The differential analog voltage input has good common. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt- age of 4. The data from the.
As can be seen, this reduces the allowed initial tolerance of the refer- ence voltage and requires correspondingly arc0802 absolute change with temperature variations. IC voltage regulators may be used for references if the. Zero error is the difference. As long as the analog V IN does not exceed the supply voltage by more than. Two on-chip diodes are tied to each analog input see Block Diagram which. The separate AGND point should always be wired to the. With an asynchronous start pulse, up to 8 clock periods may be required before the internal clock phases are proper to start the conversion process.
Output Short Circuit Current. In general, the reference voltage will require an initial.
Both are ground referenced. The converter can be operated in a pseudo-ratiometric mode. Note that spans smaller acd0802 2. In addition, the voltage reference input can be. This WR and INTR node should be momentarily forced to logic low following a power- up cycle to insure circuit operation. See Figure 17 for details. An arbitrarily wide pulse.
These converters appear to the. In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution. For example, if the span is reduced to 2. In general, the reference voltage will require an initial adjustment.
Users should follow proper IC Handling Procedures. 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. Note that spans smaller. For larger clock line loading, a CMOS or low power.

The output data latch is not updated if the. DGND, being careful to avoid ground loops. See the Zero Error description in this data sheet. The data from the previous conversion remain in this latch. However, if an all zero code is desired for an analog input other than 0V, or if a narrow full scale span.
In absolute conversion applicatIons, both the initial. With an asynchronous start pulse, up to 8 clock periods may be required before the internal clock phases are proper to start the conversion. 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: The converter can be made to output.
Restart During a Conversion. IC voltage regulators may be used for references if the ambient temperature changes are not excessive. Errors due to an improper datssheet of reference. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt.
