Part Details for LTC2496IUHF#PBF by Linear Technology

The datasheet provides some general guidelines, but a good rule of thumb is to keep the analog and digital grounds separate, use a solid ground plane, and place the ADC as close as possible to the analog signal sources. Additionally, use a low-ESR capacitor for the VREF pin and keep the input traces as short as possible.

The LTC2496IUHF#PBF has an internal calibration mechanism, but it's recommended to perform an external calibration using a high-accuracy voltage reference. This involves applying a known voltage to the input and adjusting the offset and gain registers to match the expected output code.

The maximum sampling rate of the LTC2496IUHF#PBF is 15ksps, but it can be reduced to conserve power. The power consumption increases with the sampling rate, so reducing the sampling rate can help reduce power consumption. However, this may affect the accuracy and noise performance of the ADC.

The LTC2496IUHF#PBF has internal overvoltage protection, but it's still recommended to add external protection circuitry, such as voltage clamps or resistors, to prevent damage from excessive voltage. Additionally, consider using a voltage limiter or a buffer amplifier to condition the input signal.

Yes, the LTC2496IUHF#PBF can be used in a multiplexed configuration. To handle channel switching, use an external multiplexer and ensure that the multiplexer settling time is sufficient to allow the ADC to accurately sample the input signal. Additionally, consider using a sample-and-hold circuit to freeze the input signal during the channel switching.
