EVAL-AD5668SDCZ
Analog Devices Inc.
The AD5668 device is a low power, octal, 16-bit, buffered voltage-output DAC. All devicesoperate from a single 2.7 V to 5.5 V supply and are guaranteedmonotonic by design. The AD5668 and AD5628 are available inboth a 4 mm ? 4 mm LFCSP and a 16-lead TSSOP, while theAD5648 is available in both a 14-lead and 16-lead TSSOP.The AD5628/AD5648/AD5668 have an on-chip reference withan internal gain of 2. The AD5628-1/AD5648-1/AD5668-1 havea 1.25 V 5 ppm/?C reference, giving a full-scale output rangeof 2.5 V; the AD5628-2/AD5648-2/AD5668-2 and AD5668-3 havea 2.5 V 5 ppm/?C reference, giving a full-scale output range of5 V. The on-board reference is off at power-up, allowing the useof an external reference. The internal reference is enabled via asoftware write.The part incorporates a power-on reset circuit that ensures that theDAC output powers up to 0 V (AD5628-1/AD5648-1/AD5668-1,AD5628-2/AD5648-2/AD5668-2) or midscale (AD5668-3) andremains powered up at this level until a valid write takes place.The part contains a power-down feature that reduces the currentconsumption of the device to 400 nA at 5 V and provides software-selectable output loads while in power-down mode for any or allDAC channels. The outputs of all DACs can be updated simultaneouslyusing the LDAC function, with the added functionalityof user-selectable DAC channels to simultaneously update. Thereis also an asynchronous CLR that updates all DACs to a userprogrammablecode?zero scale, midscale, or full scale.The AD5628/AD5648/AD5668 utilize a versatile 3-wire serialinterface that operates at clock rates of up to 50 MHz and iscompatible with standard SPI?, QSPI?, MICROWIRE?, andDSP interface standards. The on-chip precision output amplifierenables rail-to-rail output swing.Product Highlights Octal, 12-/14-/16-bit DAC. On-chip 1.25 V/2.5 V, 5 ppm/?C reference. Available in 14-lead/16-lead TSSOP, 16-lead LFCSP, and 16-ball WLCSP. Power-on reset to 0 V or midscale. Power-down capability. When powered down, the DAC typically consumes 200 nA at 3 V and 400 nA at 5 V. Applications Process control Data acquisition systems Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources Programmable attenuators
