The L6671 is a complete rotational accelerometer system based on a Σ∆ architecture, followed by a digital downsampling block and a digital filter, featur- ing high sensitivity, 800 Hz signal bandwidth and a complete serial port interface for a direct connection to microprocessor environment. An embedded PLL allows internal clock generation from an external syn- chronization signal.
The L6671 is a complete rotational accelerometer system based on a ZA architecture, featuring high sensitivity (2.5 rad/sec²) and an 800 Hz signal bandwidth. It includes a 7-bit A/D converter with a sign bit, digital downsampling, and digital filtering to provide a complete serial port interface for direct connection to a microprocessor environment.
The device operates with a 3.3V 3-wire serial interface (with 5V tolerance) and features an embedded PLL for internal clock generation from an external synchronization signal. It is designed for applications requiring precise angular acceleration measurement with a full-scale value of 200 rad/sec².
