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, t
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.
