PIN FUNCTION DESCRIPTIONS
Pin
No.
Mnemonic
Description
1
DUTGND_AB
Device Sense Ground for DACs A and B. VOUTA and VOUTB are referenced to the voltage
applied to this pin.
2, 44, 43,
VOUTA ..VOUTH
DAC Outputs.
41, 37, 35,
34, 32
3, 4
VREF(–)AB, VREF(+)AB
Reference Inputs for DACs A and B. These reference voltages are referred to GND.
5, 38
VDD
Positive Analog Power Supply; +15 V
± 10% for specified performance.
6VSS
Negative Analog Power Supply; –15 V
± 10% for specified performance.
7
LDAC
Load DAC Logic Input (active low). When this logic input is taken low the contents of the
registers are transferred to their respective DAC registers.
LDAC can be tied permanently
low enabling the outputs to be updated on the rising edge of
WR.
8, 9, 10
A2, A1, A0
Address inputs. A0, A1 and A2 are decoded to select one of the eight input registers for a
data transfer.
11
CS
Level-Triggered Chip Select Input (active low). The device is selected when this input is low.
12
WR
Level-Triggered Write Input (active low), used in conjunction with
CS to write data to the
AD7841 data registers. Data is latched into the selected input register on the rising edge
of
WR.
13
VCC
Logic Power Supply; 5 V
± 5%.
14
GND
Ground.
15–28
DB0 . . DB12
Parallel Data Inputs. The AD7841 can accept a straight 14-bit parallel word on DB0 to
DB13 where DB13 is the MSB and DB0 is the LSB.
29
CLR
Asynchronous Clear Input (level sensitive, active low). When this input is low, all analog
outputs are switched to the externally set potential on the relevant DUTGND pin. The con-
tents of input registers and DAC registers A to H are not affected when the
CLR pin is taken
low. When
CLR is brought back high, the DAC outputs revert to their original outputs as
determined by the data in their DAC registers.
30, 31
VREF(+)GH, VREF(–)GH
Reference Inputs for DACs G and H. These reference voltages are referred to GND.
33
DUTGND_GH
Device Sense Ground for DACs G and H. VOUTG and VOUTH are referenced to the voltage
applied to this pin.
36
DUTGND_EF
Device Sense Ground for DACs E and F. VOUTE and VOUTF are referenced to the voltage
applied to this pin.
39
VREF(+)CDEF
Reference Inputs for DACs C, D, E and F. These reference voltages are referred to GND.
40
VREF(–)CDEF
Reference Inputs for DACs C, D, E and F. These reference voltages are referred to GND.
42
DUTGND_CD
Device Sense Ground for DACs C and D. VOUTC and VOUTD are referenced to the voltage
applied to this pin.
