Description
The AD5620/AD5640/AD5660, members of the nanoDACTM family of devices, are low power, single, 12-/14-/16-bit, buffered voltage-out DACs and are guaranteed monotonic by design.
The AD5620/AD5640/AD5660-1 parts include an internal,
1.25 V, 5 ppm/°C reference, giving a full-scale output voltage
range of 2.5 V. The AD5620/AD5640/AD5660-2-3 parts include an
internal, 2.5 V, 5 ppm/°C reference, giving a full-scale output
voltage range of 5 V. The reference associated with each part is
available at the VREFOUT pin.
The parts incorporate a power-on reset circuit to ensure that the DAC output powers up to 0 V (AD5620/AD5640/AD5660-1-2) or midscale (AD5620-3 and AD5660-3) and remains there until a valid write takes place. The parts contain a power-down feature that reduces the current consumption of the device to 480 nA at 5 V and provides software-selectable output loads while in power-down mode. The power consumption is
2.5 mW at 5 V, reducing to 1 μW in power-down mode.
The AD5620/AD5640/AD5660 on-chip precision output amplifier allows rail-to-rail output swing to be achieved. For remote sensing applications, the output amplifier’s inverting input is available to the user. The AD5620/AD5640/AD5660 use a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI®, QSPITM, MICROWIRETM, and DSP interface standards.
