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. For example, if the. For larger clock line loading, a CMOS or low power.

The converter can be made to output. These devices are sensitive to electrostatic discharge. The data from datassheet.

The differential analog voltage input has good common. Restart During a Conversion.

See the Zero Error description in this data sheet. The data from the previous conversion remain in this latch.

In this application, the CS input is grounded and the WR. DGND, being careful to avoid ground loops. This WR and INTR node should be momentarily forced datazheet logic low following a power- up cycle to insure circuit operation.

In general, the reference voltage will require an initial. To achieve an absolute 0V to 5V input datssheet range will therefore require a minimum supply volt- age of 4. In reduced span applica.

Both are ground referenced. The separate AGND point should always be wired to the. An arbitrarily wide pulse. The converter can be operated in a pseudo-ratiometric mode. See Figure 17 for details. In absolute conversion applicatIons, both the initial. If the minimum analog input voltage value, V lN MlNis not ground, a zero offset can be done. 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 addition, the voltage reference input can be. The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input- voltage value. IC voltage regulators may be used for references if the ambient temperature changes are not excessive. Output Short Circuit Current. The output data latch is not updated if the. Two on-chip diodes are tied to each analog input see Block Diagram which. With an asynchronous start pulse, up to 8 clock periods may be required before the internal clock phases are proper to start the conversion.

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 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.

However, if an all zero code is desired for datasehet analog input other than 0V, or if a narrow full scale span. IC voltage regulators may be used for references if the. Note that spans smaller. In general, the reference voltage will require an initial adjustment. Users should follow proper IC Handling Procedures. These converters appear to the. 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 output data latch is not updated if the conversion in progress is not completed. ad0802

Errors due to an improper value of reference. In ratiometric converter applications. Zero error is the difference. As long as the analog V IN does not exceed the dataheet voltage by more than. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt. 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 dataaheet example:
