Low Cost Single Axis PSI5 Compatible Satellite Sensor

The ADXL716 is a g range configurable single-axis integrated satellite sensor, compliant to the Peripheral Sensor Interface 5 (PSI5) Version 2.1 specification. The ADXL716 (x-axis) enables low cost solutions for active suspension satellite sensor applications. Acceleration data is sent to the control module via a digital 2-wire current loop interface bus.

The device utilizes an error correcting code (ECC) protected one-time programmable (OTP) memory. The g range of the sensor is configurable to provide full-scale acceleration measurement of ±1.6 g or ±16 g. Additionally, the device can be configured to transmit data from multiple g ranges during predefined time slots, in accordance with the PSI5 specification. The device transmits 10-bit or 16-bit acceleration data to the control module, and can be configured to include either a 1-bit parity check, or a 3-bit cyclic redundancy check (CRC). Each device has a unique electronic serial number.

The ADXL716 is available in a 12-lead, 4 mm × 4 mm LFCSP package. The ADXL716 is specified to operate over the full automotive temperature range, from −40°C to +125°C.
