SBAS246B December 2001 – November 2014 DAC8532
PRODUCTION DATA.
PIN | NAME | FUNCTION |
---|---|---|
1 | VDD | Power supply input, 2.7 V to 5.5 V |
2 | VREF | Reference voltage input |
3 | VOUTB | Analog output voltage from DAC B |
4 | VOUTA | Analog output voltage from DAC A |
5 | SYNC | Level triggered SYNC 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 transferred on the falling edges of SCLK. The action specified by the 8-bit control byte and 16-bit data word is executed following the 24th falling SCLK clock edge (unless SYNC is taken HIGH before this edge in which case the rising edge of SYNC acts as an interrupt and the write sequence is ignored by the DAC8532). |
6 | SCLK | Serial Clock Input. Data can be transferred at rates up to 30 MHz at 5 V. |
7 | DIN | Serial Data Input. Data is clocked into the 24-bit input shift register on the falling edge of the serial clock input. |
8 | GND | Ground reference point for all circuitry on the part. |
