2.7V~3.3V 125kS/s 16bit 1 16 DSP,SPI 2.7V~3.3V String DAC SOT-23-8 , 2.9mm*1.6mm*1.15mm

Single, 16-Bit nanoDAC® with 5 ppm/°C On-Chip Reference

The AD5620/AD5640/AD5660, members of the nanoDAC family of devices, are low power, single, 12-/14-/16-bit, buffered voltage-out DA Cs and are guaranteed monotonic by design. The AD5620/AD5640/AD5660-1 parts include an internal, 1.25 V, 5 ppm/oC 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/oC 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 uW 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 amplifierR^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(R), QSPI(TM), MICROWIRE(TM), and DSP interface standards.
