GENERAL DESCRIPTION
The AD5300 is a single, 8-bit buffered voltage output DAC that
operates from a single 2.7 V to 5.5 V supply, consuming 115 μA
at 3 V. Its on-chip precision output amplifier allows rail-to-rail
output swing to be achieved. The AD5300 uses a versatile 3-wire
serial interface that operates at clock rates up to 30 MHz and is
compatible with standard SPI®, QSPI™, MICROWIRE™, and
DSP interface standards.
The reference for the AD53001 is derived from the power supply
inputs and thus gives the widest dynamic output range. The part
incorporates a power-on reset circuit that ensures that the DAC
output powers up to 0 V and remains there until a valid write takes
place to the device. The part contains a power-down feature that
reduces the current consumption of the device to 200 nA at 5 V
and provides software selectable output loads while in power-
down mode. The part is put into power-down mode over the
serial interface.
The low power consumption of this part in normal operation
makes it ideally suited to portable battery-operated equipment.
The power consumption is 0.7 mW at 5 V, reducing to 1 μW in
power-down mode.
The AD5300 is one of a family of pin-compatible DACs. The
AD5310 is the 10-bit version, and the AD5320 is the 12-bit
version. The AD5300/AD5310/AD5320 are available in 6-lead
SOT-23 packages and 8-lead MSOP packages.

PRODUCT HIGHLIGHTS
1. Available in 6-lead SOT-23 and 8-lead MSOP packages.
2. Low power, single-supply operation. This part operates from a
single 2.7 V to 5.5 V supply and typically consumes 0.35 mW
at 3 V and 0.7 mW at 5 V, making it ideal for battery-powered
applications.
3. The on-chip output buffer amplifier allows the output of
the DAC to swing rail-to-rail with a slew rate of 1 V/μs.
4. Reference derived from the power supply.
5. 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.
6. Power-down capability. When powered down, the DAC
typically consumes 50 nA at 3 V and 200 nA at 5 V.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD5300 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
