FUNCTIONAL DESCRIPTION
I
The SM5320A uses an I
1) Cutoff frequency (HD block)
2) fc mode switching (1/2 cutoff frequency switching, HD block)
3) Filter mode/filter bypass mode switching (HD block)
4) Input type switching (sync-tip clamp, bias, HD block)
5) Power-down function
6) Gain setting
The transfer rate of I
support a read function (IC is write only).
Basic Cycle
The write sequence is: SM5320A slave address → specific control register sub-address → write data. Data can
be written to the SM5320A in successive bytes, as the sub-address for the register is incremented automatically
after each byte. However, if the sub-address exceeds the address of the last register (03h), data write operation
to the SM5320A register stops and the acknowledge signal is not returned.
