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

•

Minimum/maximum values of currents are determined using corner lots over complete

temperature range

•

Minimum/maximum values of state machine timings are determined using corner lots over

0…+65 °C temperature range

The specification tables are split into pressure and temperature part of BMP280.
