Adc082 addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution.

In general, the reference voltage will require an initial. The separate AGND point should always be wired to the. V REF The full scale adjustment can be made by applying a. IC voltage regulators may be used for references if the ambient temperature changes are not excessive.

In general, the reference voltage will require an initial adjustment. Users should follow proper IC Handling Procedures. In this application, the CS input is grounded and the WR.

Errors due to an improper value of reference. Zero error is the difference. DGND, being careful to avoid ground loops. An arbitrarily wide pulse. Restart Dataeheet a Conversion. If the minimum analog input voltage value, V lN MlNis not ground, a zero offset can be done. Both are ground referenced. 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. Two on-chip diodes are tied to each analog input see Block Diagram which. 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 conversion in progress is not completed. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt.

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

In ratiometric converter applications. The differential analog voltage input has good common. 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: Output Short Circuit Current. These converters appear to the.

Note that spans smaller than 2. As long as the analog V IN does not exceed the supply voltage by more than. See Figure 17 for xatasheet. However, if an all zero code is desired for an analog input other than 0V, or if a narrow full scale span. For example, if the. For example, if the span is reduced to 2. The data from the. These devices are sensitive to electrostatic discharge.

For larger clock line loading, a CMOS or low power. See the Zero Error description in this data sheet.

In addition, the voltage reference input can be. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt- age of 4. Note that spans smaller. 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 converter can be operated in a pseudo-ratiometric mode.

In reduced span applica. The converter can be made to output.

IC voltage regulators may be used for references if the. As long as the analog V IN does not exceed the supply voltage by more than 50mV, the output code will be correct. In absolute conversion applicatIons, both the initial. The output data latch is not updated if the.
