PIN ASSIGNMENTS
Pin 1 — V
OUT 4 — Voltage Output from DAC4.
Pin 2 — V
SS — –5V Power Supply Input.
Pin 3 — V
DD — +5V Power Supply Input.
Pin 4 — CLR — Clear. Gated with WR2 (pin
11). Active low. Clears all DAC outputs to 0V.
Pin 5 — REF IN — Reference Input for DACs.
Pin 6 — GND — Ground.
Pin 7 — B1/B2 — Byte 1/Byte 2 — Selects
Data Input Format. A logic “1” on pin 7 selects
the 12–bit mode, and all 12 data bits are pre-
sented to the DAC(s) unchanged; a logic “0”
selects the 8–bit mode, and the four LSBs are
connected to the four MSBs, allowing an 8–bit
MSB–justified interface.
Pins 8 and 9 — A
0 & A1
— Address for DAC
Selection. A
1/A0 = 0/0 = DAC1; 0/1 = DAC2; 1/
0 = DAC3; 1/1 = DAC4.
Pin 10 — XFER — Transfer. Gated with WR2
(pin 11); loads all DAC registers simultaneously.
Active low.
Pin 11 — WR2 — Write Input 2 — In conjunc-
tion with XFER (pin 10), controls the transfer of
data from the input registers to the DAC regis-
ters. In conjunction with CLR (pin 4), the DAC
registers are forced to 1000 0000 0000 and the
DAC outputs will settle to 0V. Active low.
Pin 12 — WR1 — Write Input1 — In conjunc-
tion with CS (pin 13), enables input register
selection, and controls the transfer of data from
the input bus to the input registers. Active low.
Pin 13 — CS — Chip Select — Enables writing data
to input registers and/or transferring data from input
bus to DAC registers. Active low.
Pin 14 — V
OUT1 — Voltage Output from DAC1.
Pin 15 — V
OUT2 — Voltage Output from DAC2.
Pin 16 — DB
11 — Data Bit 11; Most Significant Bit.
Pin 17 — DB
10 — Data Bit 10.
Pin 18 — DB
9 — Data Bit 9.
Pin 19 — DB
8 — Data Bit 8.
Pin 20 — DB
7 — Data Bit 7.
Pin 21 — DB
6 — Data Bit 6.
Pin 22 — DB
5 — Data Bit 5.
Pin 23 — DB
4 — Data Bit 4.
Pin 24 — DB
3 — Data Bit 3.
Pin 25 — DB
2 — Data Bit 2.
Pin 26 — DB
1 — Data Bit 1.
Pin 27 — DB
0 — Data Bit 0; LSB
Pin 28 — V
OUT3 — Voltage Output from DAC3.
