AD5628ARUZ-2REEL7

AD5628 device is low power, octal, 12bit, buffered voltage-output DAC. The device operates from a single 2.7V to 5.5V supply and is guaranteed monotonic by design. It has an on-chip reference with an internal gain of 2. 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 contains a power-down feature that reduces the current consumption of the device to 400nA at 5V 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 the active-low LDAC function, with the added functionality of user-selectable DAC channels to simultaneously update. Applications include process control, data acquisition systems, portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators.

• Power-on reset circuit that ensures that the DAC output powers up to 0V
• 2.5V 5ppm/°C reference, giving a full-scale output range of 5V
• Versatile 3-wire serial interface that operates at clock rates of up to 50MHz
• Compatible with standard SPI®, QSPI™, MICROWIRE™ and DSP interface standards
• On-chip precision output amplifier enables rail-to-rail output swing
• 16-lead TSSOP package, -40°C to +105°C temperature range
• Power-on reset to code zero, ±2LSB INL accuracy, 2.5V internal reference
• Differential nonlinearity of ±0.25LSB max (VDD = 4.5V to 5.5V)
