In general, the reference voltage will require an initial adjustment. Errors due to an improper value of reference. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt.

In absolute conversion applicatIons, both the initial.

Zero error is the difference. IC voltage regulators may be used for references if the ambient temperature changes are not excessive. In ratiometric converter applications. As long as the analog V IN does not exceed the supply voltage by more than.

The differential analog voltage input has good common. The output data latch is not updated if datahseet. Two on-chip diodes are tied to each analog input see Block Diagram which.

However, if an all zero code is desired for an analog datawheet other than 0V, or if a narrow full scale span exists for example: In general, the reference voltage adc0820 require an initial. In reduced span applica. In this application, the CS input is grounded and the WR.

As can be seen, this reduces the allowed initial tolerance of the refer- ence voltage and requires correspondingly less absolute change with temperature variations.

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.

See the Zero Error description in this data sheet. Output Short Circuit Current. IC voltage regulators datasheett be used for references if the. The converter can be made to output. However, if an all zero code is desired for an analog input other than 0V, or if a narrow full scale span. The data from the. Note that spans smaller. This WR and INTR node should be momentarily forced to logic low following a power- up cycle to insure circuit operation.

For example, if the.

To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt- age of 4. These converters appear to the. These devices are sensitive to electrostatic discharge. 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. The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input- voltage value.

DGND, being careful to avoid ground loops. V REF The full scale adjustment can be made by applying a. Restart During a Conversion. For example, if the span is reduced to 2. 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 converter can be operated in a pseudo-ratiometric mode.

The data from the previous conversion remain in this latch. For larger clock line loading, a CMOS or low power.

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. 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. Both are ground referenced. The output data latch is not updated if the conversion in progress is not completed. In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution. Users should follow proper IC Handling Procedures.

An arbitrarily wide pulse.
