Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common-mode filter capacitor between the input pins and the ground plane to reduce noise.
To ensure accuracy in high-temperature applications, it's recommended to use a thermocouple or thermistor to measure the temperature and compensate for the temperature drift of the INA321EA/250G4. Additionally, the device should be operated within its specified temperature range and the PCB should be designed to minimize thermal gradients.
The recommended input impedance for the INA321EA/250G4 is 1 kΩ or higher. This ensures that the input voltage is not attenuated and the device operates within its specified common-mode range.
Yes, the INA321EA/250G4 can be used in a single-supply application, but the input common-mode voltage range is limited to VCC - 1.5V to VCC + 0.5V. Additionally, the output voltage swing is limited to VCC - 1.5V to VCC + 0.5V, so the output voltage may not reach the rail-to-rail voltage range.
To reduce noise and EMI in the INA321EA/250G4 circuit, it's recommended to use a low-pass filter at the input, a common-mode filter capacitor between the input pins and the ground plane, and to keep the input and output traces as short as possible. Additionally, the PCB should be designed to minimize electromagnetic radiation and the device should be operated in a shielded environment.
