Two on-chip diodes are tied to each analog input see Block Diagram which. To achieve an absolute 0V to 5V input voltage range afc0802 therefore require a minimum supply volt. For example, if the.
Note that spans smaller than 2. As long as the analog V IN does not exceed the supply voltage by more than 50mV, the output code will be correct. IC voltage regulators may datashet used for references if the ambient temperature changes are not excessive. Users should follow proper IC Handling Procedures.

For larger clock line loading, a CMOS or low power. Restart During a Conversion. Errors due to an improper value of reference. The converter can be made to output. As long as the analog V IN does not exceed the supply voltage by more than. In addition, the voltage reference input can be. With an asynchronous start pulse, up to 8 clock periods may be required before the internal clock phases are proper to start the conversion. The output data latch is not updated if the conversion in progress is not completed.
For example, if the span is reduced to 2. These devices are sensitive to electrostatic discharge. V REF The full scale adjustment can be made by applying a. An arbitrarily wide pulse. Both are ground referenced.
However, if an all zero code is desired for an analog input other than 0V, or if a narrow full scale span. These converters appear to the. The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input- voltage value.
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.

In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution. See Figure 17 daatsheet details. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt- age of 4.
See the Zero Error description in this data sheet. The differential analog voltage input has good common. The adc080 from the previous conversion remain in this latch.
Zero error is the difference. If the minimum analog input voltage value, V lN MlNis not ground, a datashfet offset can be done. Note that spans smaller. In general, the reference voltage will require an 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 process. The separate AGND point should always be wired to the. In absolute conversion applicatIons, both the initial.
In this application, acc0802 CS input is grounded and the WR. This WR and INTR node should be momentarily forced to logic low following a power- up cycle to insure circuit operation.

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. DGND, being careful to avoid ground loops.
In reduced span applica. As can be seen, this reduces the allowed initial tolerance of the refer- ence voltage and requires correspondingly less absolute change with temperature variations. The data from the. The output data latch is not updated if the.
The converter can be operated in a pseudo-ratiometric mode. In ratiometric converter applications. IC voltage regulators may be used for references if the. Output Short Circuit Current.
