DB0

DATA, LSB.

13

RESET

Resets output of all D/As to bipolar-zero. The D/A remains in this state until overwritten by a LDAC-WR command. RESET

does not reset the input latch. After power–up and reset, input latches will be in an indeterminant state.

14

WR

Write strobe. Must be low for data transfer to any latch (except RESET).

15

EN1

Enable for 12-bit input data latch of D/A1. NOTE: This logic path is slower than the WR/ path.

16

EN2

Enable for 12-bit input data latch of D/A2. NOTE: This logic path is slower than the WR/ path.

17

EN3

Enable for 12-bit input data latch of D/A3. NOTE: This logic path is slower than the WR /path.

18

EN4

Enable for 12-bit input data latch of D/A4. NOTE: This logic path is slower than the WR/ path.

19

LDAC

Load DAC enable. Must be low with WR for data transfer to the D/A latch and simultaneous update of all D/A converters.

20

DCOM

Digital common, logic currents return.

21
