This application note provides usage information and application hints related to ST L3G4200D 3-axial digital gyroscope.
The document describes the ST L3G4200D, a three-axis angular rate sensor with a digital I2C/SPI serial interface. Key features include selectable full-scale ranges of ±250/±500/±2000 dps, programmable interrupt thresholds and timing, and an integrated 32-level FIFO buffer to reduce host processor intervention.
The guide details the device's operating modes (power-down, sleep, normal), startup sequences, digital filter configurations for low-pass and high-pass filtering, and interrupt generation mechanisms. It also covers FIFO buffer management, temperature sensor usage, and register definitions.
| Full scale range | ±250/±500/±2000 dps |
|---|---|
| Temperature range | -40 °C to +85 °C |
| Package type | LGA 4x4x1.1 |
| Power consumption (Normal mode) | 6.1 mA |
The device provides three different operating modes: power-down mode, sleep mode, and normal mode.
The integrated 32-level FIFO buffer allows the user to store data for host processor intervention reduction.
