See AT_SEL register section. 2 nRST Reset Pin. Logic low on this pin will hold the ADCS and digital circuitry in a reset condition and clear internal registers. 3 DVDD Digital Power Supply(+5V),provides the supply voltage for the digital circuitry. It should be maintained at 5 V±5% for specified operation 4 AVDD Power Supply (+5V). Provides the supply voltage for the circuitry. It should be maintained at 5 V±5% for specified operation. 5,6 V1P,V1N Analog input for current channel, These inputs are fully differential voltage inputs with a maximum signal level of ±660 mV, Adjustable Gain. 7,8 V2N,V2P Negative and Positive Inputs for Voltage Channel. These inputs provide a fully differential input pair. The maximum differential input voltage is ± 660 mV for specified operation. Adjustable Gain. |
