TheAD5306/AD5316/ AD5326 are quad 8-/10-/12-bit buffered voltage output DACs in 16-lead TSSOP packages that operate from a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V. Their on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/μs. A 2-wire serial interface, which operates at clock rates up to 400 kHz, is used. This interface is SMBus-compatible at VDD< 3.6 V. Multiple devices can be placed on the same bus.Each DAC has a separate reference input that can be configured as buffered or unbuffered. The outputs of all DACs can be updated simultaneously using the asynchronousLDACinput. The parts incorporate a power-on reset circuit that ensures the DAC outputs power up to 0 V and remain there until a valid write to the device takes place. The software clear function clears all DACs to 0 V. The parts contain a power-down feature that reduces the current consumption of the device to 300 nA @ 5 V (90 nA @ 3 V).All three parts have the same pinout, which allows users to select the amount of resolution appropriate for their application without redesigning their circuit board.PRODUCT HIGHLIGHTSAvailable in a 16-lead MicroSOIC packageLow power, single supply operation from 2.5 V to 5.5 V supplyConsumes 1.2mW at 3 V and 2.5 mW at 5 VRail-to-Rail output with a slew rate of 0.7 V/µsMultiple devices can share the same bus2-wire serial interface with clock rates up to 400 kHzPin- and Software-Compatible with theAD5306(8-Bit) and theAD5316(10-Bit)APPLICATIONSPortable battery-powered instrumentsDigital gain and offset adjustmentProgrammable voltage and current sourcesProgrammable attenuatorIndustrial process control
