N0402P00042C6 Datasheet AD7864-1 Figure 2 shows the analog input section of the AD7864-1. Each input can be configured for +5 V or +10 V operation on the AD7864-1. For+5 V (AD7864-1) operation, the VINXA and VINXB inputs are tied together and the input voltage is applied to both. For+10 V (AD7864-1) operation, the VINXB input is tied to AGND and the input voltage is applied to the VINXA input. The VINXA and VINXB inputs are symmetrical and fully inter- changeable. Thus for ease of PCB layout on the +10 V range, the input voltage may be applied to the VINXB input while the VINXA input is tied to AGND.
