NOTES
1. An idle HI (CLK-HI) or idle LO (CLK-LO) clock may be used. Data is latched on the negative edge.
2. For SPI or Microwire 3-wire bus operation, tie
LD to WRITE and use WRITE pulse to drive both pins. (This generates an automatic internal load signal.)
3. If an idle HI clock is used, tCW and tWL are measured from the final negative transition to the idle state.
4. The first data byte selects an address (MSB HI), and subsequent MSB LO states set gain/attenuation levels. Refer to the Address/Data Decoding Truth Table.
5. Data must be sent MSB first.
