GENERAL DESCRIPTION APPLICATIONS The AD5620/AD5640/AD5660, members of the nanoDAC™ family of devices, are low power, single, 12-/14-/16-bit, buffered voltage-out DACs and are guaranteed monotonic by design. Process control Data acquisition systems Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources Programmable attenuators 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. PRODUCT HIGHLIGHTS 1. 2. 3. 4. 5. 12-/14-/16-bit nanoDAC—12-bit accuracy guaranteed. On-chip, 1.25 V/2.5 V, 5 ppm/°C reference. Available in 8-lead SOT-23, MSOP, and LFCSP packages. Power-on reset to 0 V or midscale. 10 µs settling time. Table 1. Related Device Part No. AD5662 Rev. G Description 2.7 V to 5.5 V, 16-bit DAC in SOT-23, LFCSP, and MSOP, external reference 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®, QSPI™, MICROWIRE™, and DSP interface standards.
