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

AUTOMOTIVE 87C196KD
8-BIT MODE A D CHARACTERISTICS
The 8-bit mode trades off resolution for a faster con-
version time The AD TIME register must be used
when performing an 8-bit conversion
The following specifications are tested
with OA6H in AD TIME The actual AD TIME reg-
ister is tested with all possible values to ensure
functionality but the accuracy of the A D converter
is not
