Part Details for LTC2482IDD#PBF by Linear Technology

The datasheet provides some general guidelines, but a good rule of thumb is to keep the device away from high-current carrying traces, use a solid ground plane, and keep the analog and digital sections separate. Additionally, place the device close to the analog input sources and use short, shielded cables to connect to the inputs.

The high impedance of the analog inputs can be a challenge. To mitigate this, use a buffer amplifier or an op-amp with a low output impedance to drive the inputs. Additionally, keep the input traces short and use a guard ring around the inputs to reduce noise and capacitance.

The maximum sampling rate of the LTC2482IDD#PBF is 15ksps. However, the power consumption increases with the sampling rate. To achieve the highest sampling rate, use the internal clock and ensure that the device is properly configured. Note that the power consumption can increase by up to 50% at the maximum sampling rate.

The LTC2482IDD#PBF requires a two-point calibration to ensure accurate readings. The recommended procedure is to calibrate the device at 0V and at a voltage close to the maximum input range. Use a high-accuracy voltage source and a precision resistor to generate the calibration voltages. Follow the datasheet guidelines for the calibration procedure and ensure that the device is in a stable thermal environment during calibration.

The internal voltage reference on the LTC2482IDD#PBF has a typical accuracy of ±1.5%. While it is suitable for most applications, it may not be sufficient for high-accuracy applications. If you require a higher accuracy, use an external voltage reference with a higher accuracy, such as ±0.1%. Additionally, if you need to trim the reference voltage or require a specific voltage, an external reference is recommended.
