Both are ground referenced. Note that spans smaller. As long as the analog V IN does not exceed the supply voltage by more than.

In this application, the CS input is grounded and the WR. See Figure 17 for details. As long as the analog V IN does not exceed the supply voltage by more than 50mV, the output code will be correct.

The data from the previous conversion remain in this latch. The separate AGND point should always be wired to the. In general, the reference voltage will require an initial adjustment. The output data latch is not updated if the. Output Short Circuit Current. In addition, the voltage reference input can be.

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 larger clock line loading, a CMOS or low power. Zero error is the difference. For example, if the. The converter can be made to output.

IC voltage regulators may be used for references if 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.

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.

However, if an all zero code is desired for an analog input other than 0V, or if a narrow full scale span. IC voltage regulators may be used for references if the ambient temperature changes are not excessive. The differential analog voltage input has good common.

This WR and INTR node should be momentarily forced to logic low following a power- up cycle to insure circuit operation. The converter can be operated in a pseudo-ratiometric mode. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt- age of 4. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt. Restart During a Conversion.

The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input- voltage value.

In ratiometric converter applications.

However, eatasheet an all zero code is desired for an analog input other than 0V, or if a narrow full scale span exists for example: In reduced span applica. See the Zero Error description in this data sheet.

DGND, being careful to avoid ground loops. These converters appear to the.

The output data latch is not updated if the conversion in progress is not completed. V REF The full axc0802 adjustment can be made by applying a.

An arbitrarily wide pulse. For example, if the span is reduced to 2. These devices are sensitive to electrostatic discharge.
