5 V, 12-Bit nanoDAC, Serial Interface
in MSOP and LFCSP Packages
AD5626
FEATURES GENERAL DESCRIPTION 8-lead MSOP and 8-lead LFCSP packages
Complete voltage output with internal reference
1 mV/bit with 4.095 V full scale
5 V single-supply operation
No external components required
3-wire serial interface, 20 MHz data loading rate
Low power: 2.5 mW The AD5626, a member of the nanoDACВ® family, is a complete
serial input, 12-bit, voltage output digital-to-analog converter
(DAC) designed to operate from a single 5 V supply. It contains
the DAC, input shift register and latches, reference, and a railto-rail output amplifier. The AD5626 monolithic DAC offers
the user low cost and ease of use in 5 V only systems.
Coding for the AD5626 is natural binary with the MSB loaded
first. The output op amp can swing to either rail and is set to a
range of 0 V to 4.095 V for a one-millivolt-per-bit resolution. It
is capable of sinking and sourcing 5 mA. An on-chip reference
is laser trimmed to provide an accurate full-scale output voltage
of 4.095 V. APPLICATIONS
