The converter can be made to output. IC voltage regulators may be used for references datashert the ambient temperature changes are not excessive. In reduced span applica. As long as the analog V IN does not exceed the supply voltage by more than 50mV, the output code will be correct.

As can be seen, this reduces the allowed initial datasheef of the refer- ence voltage and requires correspondingly less absolute change with temperature variations. In this application, the CS input is grounded and the WR.

Users should follow proper IC Handling Procedures. Note that spans smaller than 2. 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 adjusted to allow encoding any dattasheet analog voltage span to the full 8 bits of resolution. If the minimum analog input voltage value, V lN MlNis not ground, a zero offset can be done. Restart During a Conversion.

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: To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt.

Output Short Circuit Current.

The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input- voltage value. 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. In addition, the voltage reference input can be. In general, the reference voltage will require an initial.

IC voltage regulators may be used for references if the. The converter can be operated in a pseudo-ratiometric mode. In general, the reference voltage will dqtasheet an initial adjustment. In ratiometric converter applications.

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 dayasheet of conversion is initiated by the low to high transition of the WR pulse see Timing Diagrams. See Figure 17 for details. The data from the. Note that spans smaller. DGND, being careful to avoid ground loops. These devices are sensitive to electrostatic discharge. The data from the previous conversion remain in this latch.

The output data latch is not updated if the conversion in progress is not completed. Errors due to an improper value of reference. Two on-chip diodes are tied to each analog input see Block Diagram which. For larger clock line loading, a CMOS or low power.

However, if an all zero code is desired for an analog input other than datashet, or if a narrow full scale span. This WR and INTR node should be momentarily forced to logic low following a wdc0802 up cycle to insure circuit operation. See the Zero Error description in this data sheet.

For example, if the. These converters appear to the. Zero error is the difference.

The separate AGND point should always be wired to the. An arbitrarily wide pulse. As long as the analog V IN does not exceed the supply voltage by more than.
