Block Diagram
TLH11437 – 15
Pin Description
VOUT1(2)
The voltage output connections of the
VOUT2(23)
four DACS These provide output
VOUT3(17)
voltages in the range 03V – 28V
VOUT4(13)
VREFOUT(21)
The internal voltage reference output
The output of the reference is 265V
g
2%
VBIAS1(3)
The non-inverting inputs of the 4 output
VBIAS2(24)
amplifiers These pins set the virtual
VBIAS3(16)
ground voltage for the respective DACs
VBIAS4(15)
The allowed range is 03V – 14V
AGND(20)
The analog and digital ground pins
DGND(5)
DVCC(4 6)
The digital and analog power supply
AVCC(19)
pins The power supply range of the
DAC1054 is 45V – 55V To guarantee
accuracy it is required that the AVCC
and DVCC pins be bypassed separately
with bypass capacitors of 10 mF
tantalum in parallel with 01 mF ceramic
AU(11)
When this pin is taken low all DAC outputs
will be asynchronously updated CS must
be held high during the update AU must be
held high during Read back
VREF1(1)
The voltage reference inputs for the four
VREF2(22)
DACs The allowed range is 0V – 275V
VREF3(18)
VREF4(14)
CS(9)
The Chip Select control input This input is
active low
CLK(8)
The external clock input pin
DI(10)
The serial data input The data is clocked in
MSB first Preceding the data byte are 4 or
6 bits of instructions The read back
command requires 7 bits of instructions
DO(7)
The serial data output The data can be
clocked out either MSB or LSB first and on
either the positive or negative edge of the
clock
INT(12)
The power interrupt output On an
interruption of the digital power supply this
pin goes low Since this pin has an open
drain output a 10 kX pull-up resistor must
be connected to the supply
