3V and 5V 12-Bit Rail-to-Rail Micropower DACs Combine
Flexibility and Performance вЂ“ Design Note 127
Roger Zemke and Hassan Malik
The LTCВ®1450 and LTC1450L are complete single supply
rail-to-rail voltage output, 12-bit DACs in 24-pin SSOP
and PDIP packages. They include an output buffer ampliп¬Ѓer, a reference and a double-buffered parallel digital
interface. These DACs use a proprietary architecture
which guarantees a maximum DNL error of 0.5LSB. A
built-in power-on reset ensures that the output of the
DAC is initialized to zero scale. The LTC1450L draws 250ОјA from a 2.7V to 5.5V supply.
It can be conп¬Ѓgured for a 0V to 2.5V or 0V to 1.22V
output range. It has a 1.22V internal reference.
Flexibility with Stand-Alone Performance
The LTC1450/LTC1450L are complete stand-alone DACs
requiring no external components. Reference output,
reference input and gain setting pins provide the user
with added п¬‚exibility. The rail-to-rail buffered output can source or sink 5mA
while pulling to within 300mV of the positive supply
voltage or ground. The output swings to within a few
millivolts of either supply rail when unloaded and has
an equivalent output resistance of 40О© when driving
a load to the rails. Figure 1 shows how these DACs may typically be used.
REF HI is tied to REF OUT and REF LO and X1/X2 are …
