Description
16 to 29
22 to 35
DB0 to DB13
Parallel Data Inputs. The AD7835 can accept a straight 14-bit parallel word on DB0 to
DB13, where DB13 is the MSB and the BYSHF input is hardwired to a logic high.
Alternatively for byte loading, the bottom eight data inputs, DB0 to DB7, are used for
data loading, and the top six data inputs, DB8 to DB13, should be hardwired to a logic
low. The BYSHF control input selects whether 8 LSBs or 6 MSBs of data are being loaded
into the device.

38
DSGB
Device Sense Ground B Input. Used in conjunction with the CLR input for power-on
protection of the DACs. When CLR is low, DAC outputs VOUT3 and VOUT4 are forced to the
potential on the DSGB pin.
