APPLICATIONS
CHOOSING A REFERENCE AS POWER SUPPLY FOR
THE AD5601/AD5611/AD5621
The AD5601/AD5611/AD5621 come in tiny LFCSP and SC70
packages with less than a 100 A supply current. Because of
this, the choice of reference depends on the application
requirements. For applications with space-saving requirements,
the ADR02 is recommended. It is available in an SC70 package
and has excellent drift at 9 ppm/°C (3 ppm/°C in the R-8 package)
and provides very good noise performance at 3.4 V p-p in the 0.1
Hz to 10 Hz range.
Because the supply current required by the AD5601/AD5611/
AD5621 is extremely low, the parts are ideal for low supply
applications. The ADR395 voltage reference is recommended in
this case. It requires less than 100 A of quiescent current and
can, therefore, drive multiple DACs in one system, if required. It
also provides very good noise performance at 8 V p-p in the
0.1 Hz to 10 Hz range.

Some recommended precision references for use as supplies to
the AD5601/AD5611/AD5621 are listed in Table 7.

BIPOLAR OPERATION USING THE
AD5601/AD5611/AD5621
The AD5601/AD5611/AD5621 have been designed for single-
supply operation, but a bipolar output range is also possible
using the circuit shown in Figure 52. The circuit in Figure 52
gives an output voltage range of ±5 V. Rail-to-rail operation at
the amplifier output is achievable using an AD820 or OP295 as
the output amplifier.
