THE EXPOSED PAD MUST BE CONNECTED TO GROUND. TOP VIEW (Not to Scale) AD5453 3 SCLK 4 SDIN 1 IOUT1 2 GND 6 VDD 5 SYNC 8 RFB 7 VREF Figure 5. 8-Lead LFCSP Pin Configuration Table 4. Pin Function Descriptions Pin No1 TSOT MSOP LFCSP Mnemonic Description 1 8 8 RFB DAC Feedback Resistor. Establish voltage output for the DAC by connecting to external amplifier output. 2 7 7 VREF DAC Reference Voltage Input. 3 6 6 VDD Positive Power Supply Input. These parts can operate from a supply of 2.5 V to 5.5 V. 4 5 5 SYNC Active Low Control Input. This is the frame synchronization signal for the input data. Data is loaded to the shift register upon the active edge of the following clocks. 5 4 4 SDIN Serial Data Input. Data is clocked into the 16-bit input register upon the active edge of the serial clock input. By default, in power-up mode data is clocked into the shift register upon the falling edge of SCLK. The control bits allow the user to change the active edge to a rising edge. 6 3 3 SCLK Serial Clock Input. By default, data is clocked into the input shift register upon the falling edge of the serial clock input. Alternatively, by means of the serial control bits, the device can be configured such that data is clocked into the shift register upon the rising edge of SCLK. 7 2 2 GND Ground Pin. 8 1 1 IOUT1 DAC Current Output. N/A N/A EPAD EPAD Exposed pad must be connected to ground. 1 N/A = not applicable. |
