Description

General part information

AD5648 Series

The AD5648 device is a low power, octal, 14-bit, buffered voltage-output DAC. All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The AD5668 and AD5628 are available in both a 4 mm × 4 mm LFCSP and a 16-lead TSSOP, while the AD5648 is available in both a 14-lead and 16-lead TSSOP.The AD5628/AD5648/AD5668 have an on-chip reference with an internal gain of 2. The AD5628-1/AD5648-1/AD5668-1 have a 1.25 V 5 ppm/°C reference, giving a full-scale output range of 2.5 V; the AD5628-2/AD5648-2/AD5668-2 and AD5668-3 have a 2.5 V 5 ppm/°C reference, giving a full-scale output range of 5 V. The on-board reference is off at power-up, allowing the use of an external reference. The internal reference is enabled via a software write.The part incorporates a power-on reset circuit that ensures that the DAC output powers up to 0 V (AD5628-1/AD5648-1/AD5668-1, AD5628-2/AD5648-2/AD5668-2) or midscale (AD5668-3) and remains powered up at this level until a valid write takes place. The part contains a power-down feature that reduces the current consumption of the device to 400 nA at 5 V and provides software-selectable output loads while in power-down mode for any or all DAC channels. The outputs of all DACs can be updated simultaneously using theLDACfunction, with the added functionality of user-selectableDACchannels to simultaneously update. There is also an asynchronous CLR that updates all DACs to a userprogrammable code—zero scale, midscale, or full scale.The AD5628/AD5648/AD5668 utilize a versatile 3-wire serial interface that operates at clock rates of up to 50 MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards. The on-chip precision output amplifier enables rail-to-rail output swing.Product HighlightsOctal, 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.ApplicationsProcess controlData acquisition systemsPortable battery-powered instrumentsDigital gain and offset adjustmentProgrammable voltage and current sourcesProgrammable attenuators
