All rights reserved. Accuracy may degrade at higher clock frequencies. The net charge corresponds to with the arrival of a pulse at the WR input if the CS input is low. These transient currents occur at the leading edge of the otherwise signal the availability of a new conversion result. A conversion in progress can be interrupted by issuing another start command.

In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution. NO E As long as the analog V IN does not exceed the supply voltage by more than 50mV, the output code will be correct.

To achieve an absolute 0V to 5V input voltage range will therefore require a minimum supply volt- age of 4. 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. 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. 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: 0.

Timing Waveforms RD www. For example, if the span is reduced to 2. As can be seen, this reduces the allowed initial toler- ance of the reference voltage and requires correspondingly less absolute change with temperature variations. Note that spans smaller than 2. In general, the reference voltage will require an initial adjustment.

IC voltage regulators may be used for references if the ambient temperature changes are not excessive. If the minimum analog input voltage value, V lN MlN , is not ground, a zero offset can be done. The output data latch is not updated if the conversion in progress is not completed. The data from the previous conversion remain in this latch. This WR and INTR node should be momentarily forced to logic low following a power- up cycle to insure circuit operation.
