GND 2 8 Ground reference for all on-chip circuitry. VA 3 1 Power supply and Reference input. Should be decoupled to GND. Serial Data Input. Data is clocked into the 16-bit shift register on the falling DIN 4 7 edges of SCLK after the fall of SYNC. Serial Clock Input. Data is clocked into the input shift register on the falling SCLK 5 6 edges of this pin. Frame synchronization input for the data input. When this pin goes low, it enables the input shift register and data is transferred on the falling edges SYNC 6 5 of SCLK. The DAC is updated on the 16th clock cycle unless SYNC is brought high before the 16th clock, in which case the rising edge of SYNC acts as an interrupt and the write sequence is ignored by the DAC. NC 2, 3 No Connect. There is no internal connection to these pins. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 2 Submit Documentation Feedback Copyright © 2005–2013, Texas Instruments Incorporated Product Folder Links: DAC081S101 |
