Overview

The Semtech DF-8805 is an ultra-low power and high SNR digital sensor. It’s the world’s first integrated force sensor with a built-in analog front-end. The sensor is designed to be the world’s best single-chip force sensing solution. The digital output allows for a direct connection of the sensing solution output to a host processor via an industry standard I²C interface.THR_ADR, a dual function pin allows for a force trigger threshold to be set using an external resistor. Several internal settings are factory programmable using OTP registers.The Digital sensor is designed for Always-On applications. It offloads the host, allowing it to remain in a low-power state until woken up by the sensor through an interrupt when a pre-defined force threshold is achieved. The DF-8805 has two modes of operation, a 12-bit ultra-low power mode and a 16-bit high performance mode.The DF-8805 includes automatic sensor offset correction, and programmable temperature correction in conjunction with an on-board temperature sensor.
