GENERAL DESCRIPTION
The AD5601/AD5611/AD5621, members of the
nano
DAC
family, are single, 8-/10-/12-bit, buffered, voltage out DACs that
operate from a single 2.7 V to 5.5 V supply, consuming <100 μA
at 5 V. The parts come in a tiny SC70 package. Their on-chip
precision output amplifier allows rail-to-rail output swing to be
achieved. The AD5601/AD5611/AD5621 utilize a versatile
3-wire serial interface that operates at clock rates up to 30 MHz
and is compatible with SPI, QSPI, MICROWIRE, and DSP
interface standards.

nano
DAC D/A, tiny
SC70 Package
The reference for the AD5601/AD5611/AD5621 is derived from
the power supply inputs and, therefore, gives the widest
dynamic output range. The parts incorporate a power-on reset
circuit, which ensures that the DAC output powers up to 0 V
and remains there until a valid write to the device takes place.
The AD5601/AD5611/AD5621 contain a power-down feature
that reduces current consumption to <100 nA at 3 V, and
provides software-selectable output loads while in power-down
mode. The parts are put into power-down mode over the serial
interface. The low power consumption of these parts in normal
operation makes them ideally suited to portable battery-
operated equipment. The combination of small package and low
power makes these
nano
DAC devices ideal for level-setting
requirements such as generating bias or control voltages in
space-constrained and power-sensitive applications.
