Notes

LM358

VIN: 5V

OP1
Configured as voltage follower on voltage divider VIN/2.
Output connected to IN+ pins on MCP602 creating
a 5V/2 offset (2.436V on my board...)

OP2
Torque sensor reading. Output connected to ADC P2.2.

Torque Sensor Excitation

50kHz, 5Vpp at 10V offset

TL431C

Voltage reference. Typical 2.495V.
