185 / 190 page  185/190 ST90158 - ELECTRICAL CHARACTERISTICS A/D ANALOG SPECIFICATIONS (VDD = 4.5V TO 5.0 V) Notes: 1. “LSBs”, as used here, has a value of AVDD/256 2. Including sample time 3. It must be intended as the internal series resistance before the sampling capacitor 4. This is a typical expected value, but not a tested production parameter. If V(i) is the value of the i-th transition level (0 < i < 254), the performance of the A/D converter has been valued as follows: OFFS ET ERROR= deviation between the actual V(0) and the ideal V(0) (=1/2 LSB) GAIN ERROR= deviation between the actual V(254) and the ideal V(254) (=AVCC-3/2 LSB) DNL ERROR= max {[V(i) - V(i-1)]/LSB - 1} INL ERROR= max {[V(i) - V(0)]/LSB - i} ABS. ACCURA CY= overall max conversion error S/N ratio has been valued by sampling a sinusoidal input waveform and then calculating its Fast Fourier Transform. 2. Absolute accuracy: 2.5 LSB at 3V. Parameter Typical Minimum Maximum Units (1) Notes Conversion time 138 INTCLK (2) Sample time 87.51 INTCLK Power-up time 60 µs Resolution 8 8 bits Monotonicity GUARANTEED No missing codes GUARANTEED Zero input reading 00 Hex Full scale reading FF Hex Offset error .5 1 LSBs (1,4) Gain error .5 1 LSBs (4) Diff.
