TheAD5602/ AD5612 /AD5622, members of thenanoDAC®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 HIGHLIGHTSAvailable in 6-lead LFCSP and SC70 packages.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.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 derived from the power supply.Standard, fast and high speed mode I2C interface.Designed for very low power consumption.Power-down capability. When powered down, the DAC typically consumes <150 nA at 3 V.Power-on reset and brown out detection.APPLICATIONSProcess controlData acquisition systemsPortable battery-powered instrumentsDigital gain and offset adjustmentProgrammable voltage and current sourcesProgrammable attenuators
