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 ±3 values over lifetime,
 typical values of currents and state machine timings are determined at 25 °C,
 minimum/maximum values of currents are determined using corner lots over complete temperature range, and
 minimum/maximum values of state-machine timings are determined using corner lots over 0‒+65 °C temperature
range.
Besides the general electrical specifications, the following tables are separated for the gas, pressure, humidity and
temperature functions of the BME680.
