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.
The ADS807E/1K outputs 16-bit data in a serial format. The data can be clocked out of the device using the SCLK pin, and the data is valid on the falling edge of the SCLK. The data should be latched into a register or a microcontroller on the falling edge of the SCLK to ensure proper data capture.
The maximum sampling rate of the ADS807E/1K is 100 kSPS. However, the actual sampling rate may be limited by the system clock frequency, the conversion time, and the settling time of the analog input signal.
The ADS807E/1K does not require calibration. It has an internal calibration circuit that ensures accurate conversions. However, the device may require an external reference voltage to be connected to the REF pin to set the full-scale range of the converter.
The power consumption of the ADS807E/1K depends on the operating frequency and the supply voltage. At a supply voltage of 5V and an operating frequency of 100 kSPS, the typical power consumption is around 15 mW.
