10 / 24 page AD8385 Rev. 0 | Page 10 of 24 Pin Name Function Description SCL Serial Interface Data Clock Clock for the Serial Interface. SDI Serial Interface Data Input While the SEN input is low, one 12-bit serial word is loaded into the serial interface on the rising edges of SCL. The first four bits select the function; the following eight bits are the data used in the serial DACs. SEN Serial Interface Enable A falling edge of this input initiates a loading cycle. While this input is held low, the serial interface is enabled and data is loaded on every rising edge of SCL. The selected functions are updated on the rising edge of this input. While this input is held high, the serial interface is disabled. VAO1, VAO2 Serial DAC Voltage Output These output voltages are updated on the rising edge of the SEN input. TSTM Test Mode When this input is low, the overload protection and output mode are determined by the function programmed into the serial interface. While this input is held high, the overload protection is forced to enabled and the output mode is forced to normal, regardless of function programmed into the serial interface. TSTA Test Pin Connect this pin to DGND. MONITI Monitor Input Logic Input of the Level Shifting Inverting Edge Detector. MONITO Monitor Output Output of the Level Shifting Inverting Edge Detector. DYIN, DIRYIN, DIRXIN, DXIN, NRGIN, ENBX(1–4)IN Inverting Level Shifter Inputs Logic Input of the Inverting Level Shifters. DX, DY, DIRX, DIRY, NRG, ENBX(1–4) Inverting Level Shifter Outputs While the corresponding input voltage of these level shifters is below the threshold voltage, the output voltage at these pins is at VOH. While the corresponding input voltage of these level shifters is above the threshold voltage, the output voltage at these pins is at VOL. CLXIN, CLYIN Complementary Level Shifter Inputs Logic Input of the Complementary Level Shifters. CLX, CLXN, CLY, CLYN, Complementary Level Shifter Outputs While the corresponding input voltage of these level shifters is below the threshold voltage, the voltage at the noninverting output pins is at VOH and the voltage at the inverting outputs is at VOL. While the corresponding input voltage of these level shifters is above the threshold voltage, the voltage at the noninverting output pins is at VOL and the voltage at the inverting outputs is at VOH. |
