The maximum range of the position of datsaheet code transition is indicated by the horizontal arrow and it is guar- anteed to be no more than. The full 8 bits of resolution are therefore applied over this reduced analog input voltage range. L logic voltage levels.
PPI control word port is at port address E7. Human body model, pF discharged through a 1. Therefore, bypass capacitors should not be used at the analog inputs or the V. Output Current vs Temperature. Posted information as requested during last week’s class: LSB steps for the 8-bit. Pages – Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. F bypass capacitor at the inputs will. These signals have been renamed.
8-Bit µP Compatible A/D Converters
As shown, the risers. Heavy capacitive or DC loading of the clock R pin should be. Ratiometeric with Full-Scale Adjust.
Flow Chart for Auto-Zero Routine. Digitizing a Current Flow.
How to configure ADC 0801
Finally, if time is short and capacitive loading is high, external bus drivers must be used. For lower clock frequencies, the duty cycle limits can be. adf0801
Design on the IC. Exposed wdc0801 to the analog inputs can cause undesired digital noise and hum pickup, therefore shielded leads may be necessary in many applications.
A sample interface program is shown below. Zero error is the differ. For systems operating with a relatively slow CPU clock frequency, more time is available in which to establish proper logic levels on the bus and therefore higher capacitive loads can be driven see typical characteristics curves. Work on Lab Thus, one op amp can be elimi- nated since the differential to single ended conversion is provided by the differential input of the ADC series. The ADC series contains a circuit equivalent of the.

This is possible because the average value of the input current is a precise linear function of the differential input voltage. The full-scale adjustment should then be made with the. In general, the magnitude of the reference voltage will re. Zero-Shift and Span Adjust: LSB because the digital code appeared. One of the simplest tests is to apply a known analog input voltage to the converter and use LEDs to display the resulting digital output code as shown in.
Lab 6 Report is due NLT The converter can be made to.

The effects of quantization error have to be ac- counted for in the interpretation of the test results. As the latch enable input is still present, the Q output will. When the Z acknowledges the interrupt, the program is vectored to a data input Z subroutine. Next to each transfer function is shown datasheeet corresponding error plot. Basically, the capacitive loading of the data bus slows down the response time, even though DC specifications are still met.
