Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The analog input traces should be short and direct, and the digital output traces should be routed away from the analog inputs. Additionally, decoupling capacitors should be placed close to the device's power pins.
The gain and offset settings can be configured using the device's internal registers. The gain can be set to 1, 2, or 4, and the offset can be set to a value between -2.5V and 2.5V. The optimal settings will depend on the specific application and the desired output range. It is recommended to consult the device's datasheet and application notes for more information.
The maximum sampling rate of the ADS930E/1KG4 is 1 MSPS. The power consumption of the device increases with the sampling rate, so it is recommended to use the lowest sampling rate necessary for the application to minimize power consumption. At 1 MSPS, the device's power consumption is typically around 15mW.
The ADS930E/1KG4 has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage to the device and then reading the output code. The device's internal registers can then be adjusted to achieve the desired output range. It is recommended to consult the device's datasheet and application notes for more information on the calibration process.
The typical settling time of the ADS930E/1KG4 is around 2.5us. The settling time is the time it takes for the device's output to settle to within 1 LSB of the final value after a change in the input voltage. A shorter settling time can improve the device's performance in high-speed applications, but may also increase the device's power consumption.
