AD5626 Datasheet | Analog Devices

5 V, 12-Bit nano DAC, Serial Interface in MSOP and LFCSP Packages AD5626 Features 8-lead MSOP and 8-lead LFCSP packages plete voltage output with internal reference 1 m V/bit with 4.095 V full scale 5 V single-supply operation No external ponents required 3-wire serial interface, 20 MHz data loading rate Low power: 2.5 m W .. GENERAL DESCRIPTION The AD5626, a member of the nano DAC® family, is a plete 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 m A. An on-chip reference is laser trimmed to provide an accurate full-scale output voltage of 4.095 V. This part Features a serial interface that is high speed, threewire, DSP patible with data in (SDIN), clock (SCLK), and load strobe (LDAC). There is also a chip-select pin for connecting multiple DACs. The CLR input sets the output to zero scale at power on or upon user demand. The AD5626 is specified over the extended industrial temperature range (- 40°C to +85°C). The AD5626 is available in MSOP and LFCSP surface-mount packages.
