ZHCSBK1C December 2006 – January 2018 DAC8560
PRODUCTION DATA.
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | VDD | PWR | Power supply input, 2.7 V to 5.5 V |
2 | VREF | I/O | Reference voltage input/output |
3 | VFB | I | Feedback connection for the output amplifier. For voltage output operation, tie to VOUT externally. |
4 | VOUT | O | Analog output voltage from DAC. The output amplifier has rail-to-rail operation. |
5 | SYNC | I | Level-triggered control input (active LOW). This is the frame synchronization signal for the input data. When SYNC goes LOW, it enables the input shift register, and data is sampled on subsequent falling clock edges. The DAC output updates following the 24th clock. If SYNC is taken HIGH before the 24th clock edge, the rising edge of SYNC acts as an interrupt, and the write sequence is ignored by the DAC8560. Schmitt-Trigger logic input. |
6 | SCLK | I | Serial clock input, Schmitt-Trigger logic input. |
7 | DIN | I | Serial data input. Data is clocked into the 24-bit input shift register on each falling edge of the serial clock input. Schmitt-Trigger logic input. |
8 | GND | GND | Ground reference point for all circuitry on the device. |
