The maximum voltage that can be applied to the input pins is ±25V, but it's recommended to keep it within ±20V to ensure accurate measurements and prevent damage to the device.
The gain error and offset error can be calculated using the formulas provided in the datasheet. Gain error is typically around ±0.1% and offset error is around ±10μV. However, these values can vary depending on the specific application and operating conditions.
A good layout and PCB design is crucial for optimal performance. TI recommends using a 4-layer PCB with a solid ground plane, keeping the input traces short and shielded, and using a low-ESR capacitor for power supply decoupling. Additionally, it's recommended to keep the analog and digital grounds separate and connected only at one point.
Noise and interference can be filtered out using a combination of hardware and software techniques. Hardware techniques include using RC filters, ferrite beads, and shielding. Software techniques include using digital filtering algorithms, such as averaging or median filtering, and adjusting the gain and offset settings.
The maximum current that can be drawn from the output pin is 10mA. Exceeding this limit can cause the output voltage to droop or the device to overheat.
