The Qorvo AF-3068 represent ultra-low power and high SNR single-channel Analog Front-End devices (AFEs). They are designed to work with a broad range of industry sensors, including all Qorvo force sensors, to enable the best sensing solutions. The AFEs allow direct connection of these sensing solutions to a host processor via an industry standard I²C interface. Up to four AFEs can be connected to a host using a single I²C interface.The AF-3068 are designed for Always-On applications. They sample the sensing signals and off-load the host, allowing the host to remain asleep during tasks such as auto-calibration. In force applications, these AFEs can wake the system via an interrupt when a pre-defined force trigger level is achieved. In active mode, sampling at 100 Hz, the entire solution consumes only 5 μA. Depending on the sampling frequency, the solution has a low latency of 1 ms.The AF-3x68 is available in a 9-pin CSP package (1.16 mm x 1.16 mm x 0.475 mm) and can be used with all Qorvo sensors or any other analog sensor.
