INA1620RTWR Frequently Asked Questions (FAQs)

  • A good PCB layout for the INA1620 involves keeping the input and output traces short and away from noise sources, using a solid ground plane, and placing the input and output capacitors close to the device. TI provides a recommended layout in the datasheet and application notes.
  • The gain resistor (Rg) value depends on the desired gain and the input signal amplitude. TI provides a gain resistor calculator tool and a gain equation in the datasheet to help with the selection. A good starting point is to choose a gain that sets the maximum output voltage swing to around 90% of the supply voltage.
  • The INA1620 can handle input voltages up to ±10V differential, but the absolute maximum rating is ±12V. Exceeding this limit can damage the device. It's essential to ensure that the input voltage stays within the recommended operating range.
  • To filter out noise and interference, use a low-pass filter (LPF) or a band-pass filter (BPF) at the input stage. You can also add a capacitor in series with the input signal to block DC voltage. Additionally, use shielding and grounding techniques to minimize electromagnetic interference (EMI).
  • The INA1620 has a typical quiescent current of 1.5mA. To reduce power consumption, consider using a lower supply voltage, reducing the gain, or using the shutdown pin to turn off the device when not in use. You can also use the low-power mode (LP) to reduce the quiescent current to around 0.5mA.
