A TO D CONVERTER SPECIFICATIONS
The speed of the A D converter in the 10-bit or 8-bit
modes can be adjusted by setting the AD TIME
special function register to the appropriate value
The AD TIME register only programs the speed at
which the conversions are performed not the speed
at which it can convert correctly
The converter is ratiometric so absolute accuracy is
dependent on the accuracy and stability of V

1 ANGND and V
2 V
3 Testing is performed at V
4 The value of AD TIME must be selected to meet these specifications
NOTES
1 These values are not tested in production and are based on theoretical estimates and or laboratory test
2 DC to 100 KHz
3 Multiplexer Break-Before-Make Guaranteed

These values are expected for most parts at 25 C but are not tested or guaranteed
An ‘‘LSB’’ as used here has a value of approximately 5 mV (See Automotive Handbook for A D glossary of terms)

it supplies both the resistor ladder and the digital
portion of the converter and input port pins
For testing purposes after a conversion is started
the device is placed in the IDLE mode until the con-
version is complete Testing is performed at V
5 12V and 16 MHz operating frequency
There is an AD TEST register that allows for con-
version on ANGND and V
adjustment The absolute error listed is without do-
ing any adjustments
