Preliminary Technical Data
APPLICATIONS
CHOOSING A REFERENCE AS POWER SUPPLY FOR
AD5601/AD5611/AD5621
The AD5601/AD5611/AD5621 come in a tiny SC70 package
with less than 100 μA supply current. Because of this, the choice
of reference depends on the application requirement. For space-
saving applications, the ADR425 is available in an SC70 package
and has excellent drift at 3 ppm/°C. It also provides very good
noise performance at 3.4 μV p-p in the 0.1 Hz to 10 Hz range.
Rev. PrC | Page 16 of 20
Because the supply current required by the AD5601/AD5611/
AD5621 is extremely low, the parts are ideal for low supply
applications. The ADR293 voltage reference is recommended in
this case. This requires 15 μA of quiescent current and can,
therefore, drive multiple DACs in one system, if required.

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 in Figure 35. The circuit in Figure 35 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.
The output voltage for any input code can be calculated as
