DAC7625  
DAC7624  
DAC7625  
12-Bit Quad Voltage Output  
DIGITAL-TO-ANALOG CONVERTER  
FEATURES  
LOW POWER: 20mW  
DESCRIPTION  
The DAC7624 and DAC7625 are 12-bit quad voltage  
output digital-to-analog converters with guaranteed 12-  
bit monotonic performance over the specified tempera-  
ture range. They accept 12-bit parallel input data, have  
double-buffered DAC input logic (allowing simulta-  
neous update of all DACs), and provide a readback  
mode of the internal input registers. An asynchronous  
reset clears all registers to a mid-scale code of 800H  
(DAC7624) or to a zero-scale of 000 (DAC7625). The  
DAC7624 and DAC7625 can operateHfrom a single +5V  
supply or from +5V and –5V supplies.  
UNIPOLAR OR BIPOLAR OPERATION  
SETTLING TIME: 10µs to 0.012%  
12-BIT LINEARITY AND MONOTONICITY:  
–40°C to +85°C  
RESET TO MID-SCALE (DAC7624) OR  
ZERO-SCALE (DAC7625)  
DATA READBACK  
DOUBLE-BUFFERED DATA INPUTS  
Low power and small size per DAC make the DAC7624  
and DAC7625 ideal for automatic test equipment,  
DAC-per-pin programmers, data acquisition systems,  
and closed-loop servo-control. The DAC7624 and  
DAC7625 are available in a 28-pin plastic double-  
wide or a 28-lead SOIC package, and offer guaranteed  
specifications over the –40°C to +85°C temperature  
range.

NOTES: (1) If VSS = 0V, specification applies at code 00AH and above. (2) LSB means Least Significant Bit, when VREFH equals +2.5V and VREFL equals –2.5V,  
then one LSB equals 1.22mV. (3) All DAC outputs will match within the specified error band. (4) Ideal output voltage, does not take into account zero or full-scale  
error. (5) If VSS = –5V, full-scale 5V step. If VSS = 0V, full-scale positive 2.5V step and negative step from code FFFH to 00AH.

ESD damage can range from subtle performance degradation  
to complete device failure. Precision integrated circuits may  
be more susceptible to damage because very small parametric  
changes could cause the device not to meet its published  
specifications.  
NOTE: (1) Stresses above those listed under “Absolute Maximum Ratings”  
may cause permanent damage to the device. Exposure to absolute maximum  
conditions for extended periods may affect device reliability.

DAC7624/7625  
are set by the external voltage references (VREFL and VREFH  
,
THEORY OF OPERATION  
respectively). The digital input is a 12-bit parallel word and  
the DAC input registers offer a readback capability. The  
converters can be powered from a single +5V supply or a  
dual ±5V supply. Each device offers a reset function which  
immediately sets all DAC output voltages and DAC regis-  
ters to mid-scale (DAC7624, code 800H) or to zero-scale  
(DAC7625, code 000H). See Figures 1 and 2 for the basic  
operation of the DAC7624/25.  
The DAC7624 and DAC7625 are quad, voltage output,  
12-bit digital-to-analog converters (DACs). The architecture  
is a classic R-2R ladder configuration followed by an opera-  
tional amplifier that serves as a buffer. Each DAC has its  
own R-2R ladder network and output op-amp, but all share  
the reference voltage inputs. The minimum voltage output  
(“zero-scale”) and maximum voltage output (“full-scale”)

DAC7624/7625  
ANALOG OUTPUTS  
The current into the VREFH input depends on the DAC output  
voltages and can vary from a few microamps to approxi-  
mately 0.5 milliamp. The VREFH source will not be required  
to sink current, only source it. Bypassing the reference  
voltage or voltages with at least a 0.1uF capacitor placed as  
close to the DAC7624/25 package is strongly recommended.  
When VSS = –5V (dual supply operation), the output ampli-  
fier can swing to within 2.25V of the supply rails, guaran-  
teed over the –40°C to +85°C temperature range. With VSS  
= 0V (single-supply operation), the output can swing to  
ground. Note that the settling time of the output op-amp will  
be longer with voltages very near ground. Also, care must be  
taken when measuring the zero-scale error when VSS = 0V.  
Since the output voltage cannot swing below ground, the  
output voltage may not change for the first few digital input  
codes (000H, 001H, 002H, etc.) if the output amplifier has a  
negative offset.  
DIGITAL INTERFACE  
Table I shows the basic control logic for the DAC7624/25.  
Note that each internal register is level triggered and not  
edge triggered. When the appropriate signal is LOW, the  
register becomes transparent. When this signal is returned  
HIGH, the digital word currently in the register is latched.  
The first set of registers (the Input Registers) are triggered  
via the A0, A1, R/W, and CS inputs. Only one of these  
registers is transparent at any given time. The second set of  
registers (the DAC Registers) are all transparent when LDAC  
input is pulled LOW.  
The behavior of the output amplifier can be critical in some  
applications. Under short circuit conditions (DAC output  
shorted to ground), the output amplifier can sink a great deal  
more current than it can source. See the specification table  
for more details concerning short circuit current.  
REFERENCE INPUTS  
Each DAC can be updated independently by writing to the  
appropriate Input Register and then updating the DAC  
Register. Alternatively, the entire DAC Register set can be  
configured as always transparent by keeping LDAC LOW—  
the DAC update will occur when the Input Register is  
written.  
The reference inputs, VREFL and VREFH, can be any voltage  
between VSS+2.25V and VDD–2.25V provided that VREFH is  
at least 1.25V greater than VREFL. The minimum output of  
each DAC is equal to VREFL plus a small offset voltage  
(essentially, the offset of the output op-amp). The maximum  
output is equal to VREFH plus a similar offset voltage. Note  
that VSS (the negative power supply) must either be  
connected to ground or must be in the range of –4.75V to  
–5.25V. The voltage on VSS sets several bias points within  
the converter, if VSS is not in one of these two configura-  
tions, the bias values may be in error and proper operation  
of the device is not guaranteed.  
The double buffered architecture is mainly designed so that  
each DAC Input Register can be written at any time and then  
all DAC voltages updated simultaneously by pulling LDAC  
LOW. It also allows a DAC Input Register to be written to  
at any point and the DAC voltage to be synchronously  
changed via a trigger signal connected to LDAC.

DIGITAL TIMING  
DIGITAL INPUT CODING  
Figure 3 and Table II provide detailed timing for the digital  
interface of the DAC7624 and DAC7625.  
The DAC7624 and DAC7625 input data is in straight binary  
format. The output voltage is given by the following equa-  
tion:  
V
– VREFL • N  
(
+
)
REFH  
VOUT = VREFL  
4096  
where N is the digital input code. This equation does not  
include the effects of offset (zero-scale) or gain (full-scale)  
errors.
