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 of the ADS930E/1K can be configured using the Gain and Offset registers. The gain can be set to 1, 2, 4, or 8, and the offset can be set to a value between -1.5V and 1.5V. The specific configuration will depend on the application's requirements and the signal being measured. It's recommended to consult the datasheet and application notes for more information.
The maximum sampling rate of the ADS930E/1K is 1 kSPS. The sampling rate affects the device's power consumption, with higher sampling rates resulting in higher power consumption. At 1 kSPS, the device's power consumption is typically around 15 mW.
The ADS930E/1K has built-in overvoltage protection on the analog input pins, which can withstand voltages up to ±16.5V without damage. However, it's recommended to limit the input voltage to the specified range of -0.3V to VCC + 0.3V to ensure accurate conversion. Undervoltage conditions are not a concern, as the device will simply not convert the input signal if it's below the minimum specified voltage.
The typical settling time of the ADS930E/1K is around 2.5 μs. The settling time affects the device's performance by determining how quickly the output settles to the final value after a change in the input signal. A shorter settling time results in better performance and accuracy.
