NOTES:
† 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.)
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.
