AW86861 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 1 analog input differential channel and MUX, level 2 PGA, 11-bit offset calibration DAC, 14bit ADC and pressing algorithm).

AW86861 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. In low power consumption mode, the operating frequency of the chip is 10Hz and the power consumption is 8~13µA. Interrupt signals such as sampling completion, threshold comparison and press event trigger can be configured to output through interrupt pin.

The AW86861 is available in a WLCSP 1.41mmX1.41mmX0.34mm-16B package.
