GENERAL DESCRIPTION

The AD5310 is a single, 10-bit buffered voltage out DAC that
operates from a single +2.7 V to +5.5 V supply consuming
115 mA at 3 V. Its on-chip precision output amplifier allows rail-
to-rail output swing to be achieved. The AD5310 utilizes a ver-
satile three-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 AD5310 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 zero volts and remains there until a valid
write takes place to the device. The part contains a power-down
feature which 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 mW in
power-down mode.
The AD5310 is one of a family of pin-compatible DACs. The
AD5300 is the 8-bit version and the AD5320 is the 12-bit ver-
sion. The AD5300/AD5310/AD5320 are available in 6-lead
SOT-23 packages and 8-lead mSOIC packages.
PRODUCT HIGHLIGHTS
Available in 6-lead SOT-23 and 8-lead mSOIC packages.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.The on-chip output buffer amplifier allows the output of the
DAC to swing rail-to-rail with a slew rate of 1 V/ms.Reference derived from the power supply.High speed serial interface with clock speeds up to 30 MHz.
Designed for very low power consumption. The interface
only powers up during a write cycle.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-

ORDERING GUIDE

*RT = SOT-23; RM = mSOIC.
CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD5310 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.

TERMINOLOGY
Relative Accuracy

For the DAC, relative accuracy or Integral Nonlinearity (INL)
is a measure of the maximum deviation, in LSBs, from a straight
line passing through the endpoints of the DAC transfer func-
tion. A typical INL vs. code plot can be seen in Figure 2.
Differential Nonlinearity

Differential Nonlinearity (DNL) is the difference between the
measured change and the ideal 1 LSB change between any two
adjacent codes. A specified differential nonlinearity of –1 LSB
maximum ensures monotonicity. This DAC is guaranteed
monotonic by design. A typical DNL vs. code plot can be seen
in Figure 3.
Zero-Code Error

Zero-code error is a measure of the output error when zero code
(000 Hex) is loaded to the DAC register. Ideally the output
should be 0 V. The zero-code error is always positive in the
AD5310 because the output of the DAC cannot go below 0 V.
It is due to a combination of the offset errors in the DAC and
output amplifier. Zero-code error is expressed in mV. A plot of
zero-code error vs. temperature can be seen in Figure 6.
Full-Scale Error

Full-scale error is a measure of the output error when full-scale
code (3FF Hex) is loaded to the DAC register. Ideally the out-
put should be VDD – 1 LSB. Full-scale error is expressed in
percent of full-scale range. A plot of full-scale error vs. tem-
perature can be seen in Figure 6.
Gain Error

This is a measure of the span error of the DAC. It is the devia-
tion in slope of the DAC transfer characteristic from ideal
expressed as a percent of the full-scale range.
Total Unadjusted Error

Total Unadjusted Error (TUE) is a measure of the output error
taking all the various errors into account. A typical TUE vs.
code plot can be seen in Figure 4.
Zero-Code Error Drift

This is a measure of the change in zero-code error with a
change in temperature. It is expressed in mV/°C.
Gain Error Drift

This is a measure of the change in gain error with changes in
temperature. It is expressed in (ppm of full-scale range)/°C.
Digital-to-Analog Glitch Impulse

Digital-to-analog glitch impulse is the impulse injected into the
analog output when the input code in the DAC register changes
state. It is normally specified as the area of the glitch in nV secs
and is measured when the digital input code is changed by
1 LSB at the major carry transition (1FF Hex to 200 Hex). See
Figure 19.
Digital Feedthrough

Digital feedthrough is a measure of the impulse injected into the
analog output of the DAC from the digital inputs of the DAC
but is measured when the DAC output is not updated. It is
specified in nV secs and is measured with a full-scale code
change on the data bus, i.e., from all 0s to all 1s and vice versa.
