说明

AW86874 is a chip of force touch AFE, which has the functions of pressure sensing signal acquisition, amplification and processing. It integrated 1 I²C module, 1 system control module, 1 power management module and 1 AFE module (Include 4 analog input differential channel and MUX, level 2 PGA, 12-bit offset calibration DAC, 14-bit ADC).

AW86874 can enter low power consumption mode automatically without the master participation and trigger AFE work through SWDT wake-up to sample and process the signal. Interrupt signals such as sampling completion, threshold comparison and press event trigger can be configured to output through interrupt pin.

AW86874 can be used as AFE to provide the collected raw data for pressing. It can also be used as a pressure recognition module to provide the master with pressing flags.
