2.3. Electrical Parameters
All parameter values in this section are valid under the operating conditions specified in section 2.2. All voltages
referenced to VSSA.
Note: All parameters measured/validated for rADC = 14-bit; segmentation of 1st and 2nd ADC stage = 8/6;
fOSC = 8MHz; analog gain = ~100; TAMB_TQE (see specification 2.2.2).

ZSSC4151 Datasheet
4 Reliability and RoHS Conformity
The ZSSC4151 is qualified according to the AEC-Q100 standard, operating temperature grade 0. The qualifica-
tion is extended to 3000h for the High Temperature Operating Life (HTOL) Test for one lot. Two manufacturing
lots of extended HTOL qualification data (minimum of 3000h test time) for the ZSSC4151 or other products using
identical technology (metallization), the same package supplier, the same package style, and the same die size
within a specific tolerance are used to prove the package and bond reliability in the range of 3000h HTOL.
A FIT rate ≤ 10 FIT (temperature = 55°C, confidence level = 60%) is guaranteed. A typical FIT rate of TSMC’s
CV018BCD technology, which is used for the ZSSC4151, is 1 FIT.
The ZSSC4151 complies with the RoHS directive and does not contain hazardous substances.
