1)

No measurement in mass production; parameter is guaranteed by design and/or quality observation.

2)

In PWM Mode with Low-Side Switch (LSS) and PWM Mode with High-Side Switch (HSS), the sensor connection check (SCC) and the sensor short

check (SSC) diagnostics are

available only for ZSSC3170 silicon revision “F” and any subsequent revisions

3)

For complete specification, see the ZSSC3170 LIN Interface Description.

4)

2-step A/D conversion (ADCORD=1), 14-bit resolution (ADCRES=1), resolution 2nd conversion step 5-bit (ADCMODE=11)

5)

2-step A/D conversion (ADCORD=1), 14-bit resolution (ADCRES=1), resolution 2nd conversion step 2-bit (ADCMODE=00)

6)

Deviation from ideal line including INL, gain, offset, and temperature errors.

7)

With XZC active: additional total error of max. 25ppm/K at XZC = 31. Error decreases linearly at XZC < 31.
