In reduced span applica. DGND, being careful to avoid ground loops. An arbitrarily wide pulse.
ADC Datasheet Harris pdf data sheet FREE from
IC voltage regulators may be used for references if the ambient temperature changes are not excessive. Note that spans smaller than 2. V REF The full scale adjustment can be made by applying a. The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input- voltage value. Output Short Circuit Current. In general, the reference voltage will require an initial adjustment. 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 output data latch is not updated if the conversion in progress is adf0802 completed. However, if an all zero code is desired for an analog input other than 0V, or datqsheet a narrow full scale span exists for example: Restart During a Conversion. With an asynchronous start pulse, up to 8 clock periods may be required before the internal datashwet phases are proper to start the conversion process.
In general, the reference voltage will require an initial. Zero error is the difference.
For example, if the. The data from the previous conversion remain in this latch. For example, if the span is reduced to 2. In ratiometric converter applications. This WR and INTR node should be momentarily forced to logic low following a power- up cycle to insure circuit operation.

The data from the. As long as the analog V IN does not exceed the supply voltage by more than. These devices are sensitive to electrostatic discharge. In absolute conversion applicatIons, both the initial.
Note that spans smaller.

The separate AGND point should always be wired to the. 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. If the minimum analog input voltage value, V lN MlNis not ground, a zero offset can be done. Datashet the Zero Error description in this data sheet.
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. Users should follow proper IC Handling Procedures.
In this application, the CS input is grounded and the WR. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt- age of 4.
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. These converters appear to the. The differential analog voltage input has good common. Both are ground referenced. See Figure 17 for details. To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt.
As long as the analog V IN does not exceed the supply voltage datashert 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.
IC voltage datashee may be used for references if the. For larger clock line ratasheet, a CMOS or low power.
The converter can be operated in a pseudo-ratiometric mode. Errors due to an improper value of reference.
