1. Specification

If not stated otherwise,

•

All values are valid over the full voltage range

•

All minimum/maximum values are given for the full accuracy temperature range

•

Minimum/maximum values of drifts, offsets and temperature coefficients are ±3σ values over lifetime

•

Typical values of currents and state machine timings are determined at 25 °C

•

Typical values of currents and state machine timings are determined at 25°C. minimum/maximum values of currents

are determined at -40°C/85°C.

•

Minimum/maximum values of state machine timings are determined using corner lots over 0…+65 °C temperature

range.
