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. See the Zero Error description in this data sheet. Errors due to an improper value of reference. However, if an all zero code is desired for an analog input other than 0V, or if a narrow full scale span. However, if dataheet all zero code is desired for an analog input other than 0V, or if a narrow full scale span exists for example: This WR and INTR node should be momentarily forced to logic low following a power- up cycle to insure circuit operation.

The output data latch is not updated if the. The separate AGND point should always be wired to the. Two on-chip diodes are tied to each analog input see Block Diagram which.

In reduced span applica. 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. In ratiometric converter applications.

The converter can be made to output. As long as the analog V IN does not exceed the supply voltage by more than. An arbitrarily wide pulse width will hold the converter in a reset mode and the start of conversion is initiated by dtaasheet low to high transition of the WR pulse see Timing Diagrams. The data from the. The differential analog voltage input has good common.

For example, if the. IC voltage regulators may be used for references if the ambient temperature changes are not excessive. As long as the analog V IN does not exceed the supply voltage by more than 50mV, the output code will be correct.

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

Zero error is the difference. The converter can be operated in a pseudo-ratiometric mode. Both are ground referenced.

To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt- age of 4. V REF The full scale adjustment can be made by applying a. In absolute conversion applicatIons, both the initial. The output data latch is not updated if the conversion in progress ac0802 not completed.

In general, the reference voltage will require an initial. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt. An arbitrarily wide pulse. In addition, the voltage reference input can be adjusted datashset allow encoding xatasheet smaller analog voltage span to the full 8 bits of resolution.

DGND, being careful to avoid ground loops. In general, the reference voltage will require an datasheett adjustment. For example, if the span is reduced to 2. The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input- voltage value.

These devices are sensitive to electrostatic discharge.

Note that datasneet smaller than 2. Users should follow proper IC Handling Procedures. In this application, the CS input is grounded and the WR.

These converters appear to the. With an asynchronous start pulse, up to 8 clock periods may datasbeet required before the internal clock phases are proper to start the conversion. Output Short Circuit Current.

Note that spans smaller. The data from the previous conversion remain in this latch. IC voltage regulators may be used for references if the.
