GENERAL DESCRIPTIONThe AD7390/AD7391 family of 10-bit and 12-bit voltage-
output digital-to-analog converters is designed to operate
from a single 3 V supply. Built using a CBCMOS process,
these monolithic DACs offer the user low cost, and ease-of-use
in single-supply 3 V systems. Operation is guaranteed over the
supply voltage range of 2.7 V to 5.5 V consuming less than 100 µA
making this device ideal for battery operated applications.
The full-scale voltage output is determined by the external
reference input voltage applied. The rail-to-rail REFIN to
DACOUT allows for a full-scale voltage set equal to the positive
supply VDD or any value in between.
A doubled-buffered serial-data interface offers high-speed,
3-wire, SPI and microcontroller compatible inputs using data
in (SDI), clock (CLK) and load strobe (LD) pins. Addition-
ally, a CLR input sets the output to zero scale at power on or
upon user demand.
Both parts are offered in the same pinout to allow users to select
the amount of resolution appropriate for their application without
circuit card redesign.
The AD7390/AD7391 are specified over the extended industrial
(�40°C to �85°C) temperature range. The AD7391AR is
specified for the �40°C to �125°C automotive temperature
range. The AD7390/AD7391s are available in plastic DIP, and
low profile 1.75 mm height SO-8 surface mount packages. The
AD7391ARU is available for ultracompact applications in a thin
1.1mm TSSOP-8 package.

NOTES
1One LSB = VREF/4096 V for the 12-bit AD7390.
2The first two codes (000H, 001H) are excluded from the linearity error measurement.
3These parameters are guaranteed by design and not subject to production testing.
4Typicals represent average readings measured at 25°C.
5All input control signals are specified with tR = tF = 2 ns (10% to 90% of 3 V) and timed from a voltage level of 1.6 V.
6The settling time specification does not apply for negative going transitions within the last 3 LSBs of ground.
