General description
UM1478
With the mounted resistor values this gives:
●
●
V_bias=1.86 V
V signal = 2,92 ⋅ R sense ⋅ I
The maximum current manageable without distortion is equal to:
Equation 3
Note that the IMAX value can be modified by simply changing the value of the sense
resistors.

STM32F103CB microcontroller
The STM32F103xx performance line family incorporates the high-performance ARM
Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency, high-speed embedded
memories (Flash memory up to 128 Kbytes and SRAM up to 20 Kbytes), and an extensive
range of enhanced I/Os and peripherals connected to two APB buses. All devices offer two
12-bit ADCs, three general purpose 16-bit timers plus one PWM timer, as well as standard
and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs, a USB
and a CAN.
The STM32F103xx medium-density performance line family operates from a 2.0 to 3.6 V
power supply. It is available in both the -40 to +85 °C temperature range and the -40 to +105
°C extended temperature range. A comprehensive set of power-saving modes allows the
design of low-power applications.
The STM32F103xx medium-density performance line family includes devices in 5 different
package types: from 36 pins to 100 pins. Depending on the device chosen, different sets of
peripherals are included. Please refer to the STM32F103xB datasheet for an overview of the
complete range of peripherals proposed in this family.
Figure 9 shows the general block diagram of the device family.
It is possible to get more information regarding the features of the microcontroller and its
operating mode in the STM32F103xx reference manual.
