4 / 38 page  LTC6802-1 4 68021fa Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The ADC specifications are guaranteed by the Total Measurement Error (VERR) specification.

V+ = 43.2V, V– = 0V, unless otherwise noted. Note 3: Due to the contact resistance of the production tester, this specification is tested to relaxed limits. The 20Ω limit is guaranteed by design. Note 4: VCELL refers to the voltage applied across the following pin combinations: Cn to Cn-1 for n = 2 to 12, C1 to V–. VTEMP refers to the voltage applied from VTEMP1 or VTEMP2 to V–. Note 5: These absolute maximum ratings apply provided that the voltage between inputs do not exceed their absolute maximum ratings. |
