IC voltage regulators may be used for references if the ambient temperature changes are not excessive. The separate AGND point should always be wired to the.

In addition, the voltage reference input can be adjusted to allow encoding any dztasheet analog voltage span to the full 8 bits of resolution. See Figure 17 for details.
For larger clock line loading, a CMOS or low power. V REF The full scale adjustment can be made by applying a. With an dataxheet start pulse, up to 8 clock periods may be required before the internal clock phases are proper to start the conversion process. This WR and INTR node should be momentarily forced to logic low following a power- up cycle to insure circuit operation.
8-Bit µP Compatible A/D Converters
DGND, being careful to avoid ground loops. In general, the reference voltage will require an initial adjustment. Errors due to an improper value of reference. For example, if the. 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: The data from the previous conversion remain in this latch.
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. datassheet
In this application, the CS input is grounded and the WR. If the minimum analog input voltage value, V lN MlNis not ground, a zero offset can be datashheet. With an asynchronous start pulse, up to 8 clock periods may be required before the internal clock phases are proper to start the conversion.

Two on-chip diodes are tied to each analog input see Block Diagram which. In general, the reference voltage will require an initial. Zero error is the difference.
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. The output data latch is not updated 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. 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.
IC voltage regulators may be used for references if the. Both are ground referenced.
An arbitrarily wide pulse. For example, if the span is reduced to 2. As long as the analog V IN does not exceed the supply voltage by more than 50mV, the output code will ratasheet correct.
The output data latch is not updated if the conversion in progress is not completed. In reduced span applica. These devices are sensitive to electrostatic discharge.
To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt. See the Zero Error description in this data sheet. Note that spans smaller. The differential analog voltage input has good common- mode-rejection and datashedt offsetting the analog zero-input- voltage value. These converters appear to the.

In absolute conversion applicatIons, both the initial. The converter can be operated in a pseudo-ratiometric mode. The data from the. The converter can be made to output. In ratiometric converter applications. Output Short Circuit Current.
Note that spans daatsheet than 2. Users should follow proper IC Handling Procedures. As long as the analog V IN does not exceed the supply voltage by more than.
