AD5611 2.7 V to 5.5 V, <100 µA, 10-Bit nanoDAC®, SPI Interface in LFCSP and SC70

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. Product Highlights Available in 6-lead LFCSP and SC70 packages. Low power, single-supply operation. The AD5601/ AD5611/AD5621 operate from a single 2.7 V to 5.5 V supply with a maximum current consumption of 100 μA, making them ideal for battery-powered applications. The on-chip output buffer amplifier allows the output of the DAC to swing rail-to-rail with a typical slew rate of 0.5 V/μs. Reference is derived from the power supply. High speed serial interface with clock speeds up to 30 MHz. Designed for very low power consumption. The interface powers up only during a write cycle. Power-down capability. When powered down, the DAC typically consumes 0.2 μA at 3 V. Power-on reset with brownout detection. Applications Voltage level setting Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources Programmable attenuators

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.
