I/O description
Figure 2. I/O description
● Input (Vin-Gin):
The input voltage can range from 1.8 V to 14 V. If the input voltage is between 4.5 V and 14
V it can supply also the device (through the Vcc pin) and in this case the pin 1 and 2 of the
jumper G1 must be connected together.
● Output (Vout-Gout):
The output voltage is fixed at 3.3 V but it can be changed by replacing the resistor R14 of the
output resistor divider:
V_O = V_REF • _⎝⎛1 + ^RR-----¹¹---⁶⁴-_⎠⎞
