18．Op-Amps/Analog Comparators
received via an input port and feeds its output voltage into a 12-bit successive-approximation
analog-to-digital (A/D) converter(s). These op-amps are used to amplify voltage differentials
across shunt resistors for motor current measurement. The output of each op-amp is also fed into
an analog comparator and compared to the corresponding reference voltage derived from an
external resistor. The comparator provides an abnormal current indication to the EMG logic.
3-shunt resistor
1-shunt resistor
The TMPM370 has four op-amps and analog comparators. Each op-amp amplifies a voltage
Figure 18-1 shows the block diagram of the op-amps/analog converters.
