Item Description

AD Analog Input function

◆ converter type: ADS774JP

◆Input Range: ± 10V, ± 5V, 0 ~ 10V

◆ Conversion Accuracy: 12 (Bit)

◆ Sample Rate: the highest rate of 100KHz

◆ sampling channel: software-selectable, by setting the first channel to achieve the end (Last Channel – First Channel + 1)

◆ physical channel: 16 channels (single-port SE), 8 channel (double-port DI)

◆ channel switching mode: the first and the end channel switching in proper order (software trigger switch, only the issue of reading the data when they switch the order)

◆ Analog Input mode: single-ended analog input and dual-ended analog input (also known as two-terminal differential input) ◆ amplifier type: INA128P

◆ amplifier gain G and the resistance of computing RG1 relationship: G = 1 + 50KΩ / RG1 Notes: amplifier gain and resistor RG1 correspondence as shown in table 1.

◆ Analog input impedance: > 100MΩ

◆ System measurement accuracy: 0.1%
