Description
2.7 V to 5.5 V, <100 μA, 14-bit
nanoDAC
in
SC70 and LFCSP packages
APPLICATIONS
Voltage level setting
Portable battery-powered instruments
Digital gain and offset adjustment
Programmable voltage and current sources
Programmable attenuators
They also provide 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 equip-
ment. The combination of small package and low power makes
these
nanoDAC
devices ideal for level-setting requirements,
such as generating bias or control voltages in space-constrained
and power-sensitive applications.
GENERAL DESCRIPTION
The
AD5601/AD5611/AD5621,
members of the
nanoDAC®
family, are single, 8-/10-/12-bit, buffered voltage output DACs
that operate from a single 2.7 V to 5.5 V supply, consuming
typically 75 μA at 5 V. The parts come in tiny LFCSP and SC70
packages. 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.
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 typically 0.2 μA at 3 V.
PRODUCT HIGHLIGHTS
1.
2.
Available in 6-lead LFCSP and SC70 packages.
Low power, single-supply operation. The
AD5601/
AD5611/AD5621
operate from a single 2.7 V to 5.5 V
supply with a maximum current consumption of 100 μA,
making them ideal for battery-powered applications.
The on-chip output buffer amplifier allows the output of
the DAC to swing rail-to-rail with a typical slew rate of
0.5 V/μs.
Reference is derived from the power supply.
High speed serial interface with clock speeds up to
30 MHz. Designed for very low power consumption.
The interface powers up only during a write cycle.
Power-down capability. When powered down, the DAC
typically consumes 0.2 μA at 3 V. Power-on reset with
brownout detection.
