ADI AD5622BKSZ-2REEL7

The AD5602/AD5612/AD5622 are single 8-, 10-, 12-bit buffered voltage-out digital-to-analog converters (DAC) that operate from a single 2.7 V to 5.5 V supply, consuming <100 µA at 5 V. These DACs come in tiny LFCSP and 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 derive from the power supply inputs to give the widest dynamic output range. Each device 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 devices 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 for use in portable, battery operated equipment. The typical power consumption is 0.4 mW at 5 V.
