The AD5602/AD5612/AD5622, members of the _nano_DAC® family, are single 8-/10-/12-bit buffered voltage-out DACs that operate from a single 2.7 V to 5.5 V supply, consuming <100 µA at 5 V. The AD5602/AD5612/AD5622 comes in a tiny LFCSP and SC70 packages. Each DAC contains an on-chip precision output amplifier allows rail-to-rail output swing to be achieved.
The AD5602/AD5612/AD5622 utilizes a 2-wire I2C-compatible serial interface that operates in standard (100 KHz), fast (400 KHz) and high speed (3.4 MHz) modes.
The references for AD5602/AD5612/AD5622 are derived from the power supply inputs and to give the widest dynamic output range. Each part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place to the device. The devices contain a power-down feature that reduces the current consumption of the device to <150 nA at 3 V and provides software selectable output loads while in power-down mode. The devices are put into power-down mode over the serial interface. The low power consumption of the AD5602/AD5612/AD5622 in normal operation makes them ideally suited to portable, battery operated equipment. The power consumption is 0.4 mW at 5 V.
**Product Highlights**
1. Available in 6-lead LFCSP and SC70 packages.
2. Max 100µA power consumption, single-supply operation. These devices operate from a single 2.7 V to 5.5 V supply and typically consumes 0.2 mW at 3 V and 0.4 mW at 5 V, making it ideal for battery-powered applications.
3. 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.
4. Reference derived from the power supply.
5. Standard, fast and high speed mode I2C interface.
6. Designed for very low power consumption.
7. Power-down capability. When powered down, the DAC typically consumes <150 nA at 3 V.
8. Power-on-reset and brown out detection.
**Applications**
Process control
Data acquisition systems
Portable battery-powered instruments
Digital gain and offset adjustment
Programmable voltage and current sources
Programmable attenuators
