Hi Viraj, The maximum input current will occur when Vout is shorted to ground and the short circuit output current is limited to 30mA (typ). There will be some additional supply current for the device approximately 5mA on AVDD. The LDOs you have chosen should have no problem with the power requirements of two DAC8760s. 1. Yes, you can use TPS7A49 to produce AVDD for both devices and TPS7A30 for AVSS of both. Make sure that the LDOs can handle the power dissipation from a thermal perspective. 2. Yes, the two devices can share SCLK, SDO, and SDI. Latch will be used to select which device is being communicated with. This is a standard SPI bus configuration. Alternatively, the devices can be configured in daisy chain mode as explained in 8.5.1.5 of the datasheet. This eliminates the need for controlling the latch signals for the devices independently. Thanks, Garrett
