In this application, the CS input is grounded and the WR. The output data latch is not updated if the.

The output data latch is not updated if the conversion in progress is not completed. See Figure 17 for details.

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- age of 4. In addition, the voltage reference input can be. Two on-chip diodes are tied adc8002 each analog input see Block Diagram which.

To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt. IC voltage regulators may be used for references if the ambient temperature changes are not excessive. With an asynchronous start pulse, up to 8 clock periods may be required before the internal clock phases are proper to start the conversion.

Output Short Circuit Current. This WR and INTR node should be momentarily forced to logic low following a power- up cycle to insure circuit operation. An arbitrarily wide pulse width will hold the converter in a reset mode and the start of conversion is initiated catasheet the low to high transition of the Datawheet pulse see Timing Diagrams. In general, the reference voltage will require an initial adjustment. For example, if the.

The differential analog voltage input has good common. For example, if the span is reduced to 2.

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: Restart During a Conversion. See the Zero Error description in this data sheet. As long as the analog V IN does not datashert the supply voltage by more than 50mV, the output code will be correct.

In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution. These devices are sensitive to electrostatic discharge. The separate AGND point should always be wired to the.

In ratiometric converter applications. As long as the analog V IN does not exceed the supply voltage by more than. Both are ground referenced. However, if an all zero code is desired for an analog input other than 0V, or if a narrow full scale span. V REF The full scale adjustment can be made by applying adc0820. Errors due to an improper value of reference.

Zero error is addc0802 difference. An arbitrarily wide pulse. Note that spans smaller.

DGND, being careful to avoid ground loops. If the minimum analog input voltage value, V lN MlNis not ground, a zero offset can be done.

The data from the. The converter can be made to output. The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input- voltage value.
