The AD5601/AD5611/AD5621, members of the nanoDAC® family, are single, 8-/10-/12-bit, buffered voltage output DACs that operate from a single 2.7 V to 5.5 V supply, consuming typically 75 μA at 5 V. The parts come in a tiny LFCSP and SC70 packages. Their on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5601/AD5611/AD5621 utilize a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards.
The reference for the AD5601/AD5611/AD5621 is derived from the power supply inputs and, therefore, gives the widest dynamic output range. The parts incorporate a power-on reset circuit, which ensures that the DAC output powers up to 0 V and remains there until a valid write to the device takes place.
The AD5601/AD5611/AD5621 contain a power-down feature that reduces current consumption to typically 0.2 μA at 3 V. They also provide software-selectable output loads while in power-down mode. The parts are put into power-down mode over the serial interface.
The low power consumption of these parts in normal operation makes them ideally suited to portable battery-operated equipment. The combination of small package and low power makes these nanoDAC devices ideal for level-setting requirements, such as generating bias or control voltages in space-constrained and power-sensitive applications.

Healthcare at Home (Part II)
A major trend in medicine is to move treatments and monitoring out of the hospital or even the doctor's office and either attach them to the patient or enable it to be done in the home. What can device designers do to aid this effort and what technologies would help to enable it.
