• Manufacturer Part Number: 87C196KD
• Description: 16-BIT HIGH PERFORMANCE CHMOS MICROCONTROLLER
• Manufacturer: Intel Corporation

10-BIT A D CHARACTERISTICS
The speed of the A D converter in the 10-bit mode
can be adjusted by setting a clock prescaler on or
off At high frequencies more time is needed for the
comparator to settle The maximum frequency with
the clock prescaler disabled is 6 MHz The conver-
sion times with the prescaler turned on or off is
shown in the table below The AD TIME register
has not been characterized for the 10-bit mode
The converter is ratiometric so the absolute accura-
cy is dependent on the accuracy and stability
NOTES
1 DC to 100 KHz
2 Multiplexer Break-Before-Make Guaranteed
3 Typical values are expected for most devices at 25 C
An ‘‘LSB’’ as used here has a value of approximately 5 mV
