The AD5602/AD5612/AD5622, members of the nanoDAC family, are single, 8-/10-/12-bit buffered voltage-out DA Cs that operate from a single 2.7 V to 5.5 V supply, consuming <100 uA at 5 V. These DA Cs come in tiny SC70 packages. Each DAC contains an on-chip precision output amplifier that allows rail to-rail output swing to be achieved. The AD5602/AD5612/AD5622 use 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 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 parts contain a power-down feature that reduces the current consumption of the devices to <100 nA at 3 V and provides 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 the AD5602/AD5612/AD5622 in normal operation makes them ideally suited for use in portable battery-operated equipment. The typical power consumption is 0.4 mW at 5 V.
