SAR latches and the shift register stages are reset. 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.
For simplicity, the CS decoding is shown using.
If the results of this test are automatically. Logical “1” Output Voltage. For acceptance testing, the plot is not.

Each tread the range. This is due to on-chip stray.
The maximum range of the position of the code. At higher clock frequencies accuracy can degrade. If the analog input voltage were.
Effect of Unadjusted Offset Error vs. The allowed range of analog input voltages usually places. Operates ratiometrically or with 5 V. Linearity Error at Low V.
This continues for 8 approximations and the differential output adtasheet con- verges to within 5 mV of zero.

Digitizing a Current Flow. In addition, the voltage reference input can be adjusted to allow encoding any datawheet analog voltage span to the full 8 bits of resolution. When the Z acknowledges the interrupt, the program is vectored to a data input Z subroutine. Absolute with a 5V Reference.
In general, the magnitude of the reference voltage will re. Uses Chebyshev implementation for steeper roll-off unity-gain, 2nd order, low-pass filter Adding a separate filter for each channel increases system response time if an analog multiplexer is used. The effects of quantization error have to be ac- counted for in the interpretation of the test results.
Input bypass capacitors, placed from the analog. The following subroutine performs essentially the same func- tion as in the case of the A interface and it can be called from anywhere in the user’s program. In reduced span applications, the initial value. If not already accomplished Note that spans smaller than 2. Once called, this routine initializes the. LSB away from each center-value.
The 16 data bytes are stored in 16 successive memory locations.
datasheeet The value of the. An example of the use of an adjusted reference voltage is to accommodate a reduced span — or dynamic voltage range of the analog input voltage. The horizontal scale is analog input. If a full-scale adjustment is to be made, an analog input voltage of 5.
The voltage on this capacitance is switched and will result in. Table 1 shows the fractional.

LSB less than the desired. The converter is started by having CS and WR simulta- neously catasheet. To transfer analog data from several channels to a single microprocessor system, a multiple converter scheme pre- sents several advantages over the conventional multiplexer single-converter approach.
The error plots always have a constant negative slope and the abrupt up- side steps are always 1 LSB in magnitude. All voltages are measured with respect to Gnd, unless otherwise specified. If the voltage source datasheey to the V. A flow chart for the zeroing subroutine is shown in.
