Available in 6-lead LFCSP and SC70 packages. 2. Maximum 100 A power consumption, single-supply family, are single 8-, 10-, 12-bit buffered voltage-out digital-to- analog converters (DAC) that operate from a single 2.7 V to operation. These devices operate from a single 2.7 V to 5.5 V 5.5 V supply, consuming <100 A at 5 V. These DACs come in supply, typically consuming 0.2 mW at 3 V and 0.4 mW at tiny LFCSP and SC70 packages. Each DAC contains an on-chip 5 V, making them ideal for battery-powered applications. precision output amplifier that allows rail-to-rail output swing 3. The on-chip output buffer amplifier allows the output of to be achieved. the DAC to swing rail-to-rail with a typical slew rate of 0.5 V/s. 2 The AD5602/AD5612/AD5622 use a 2-wire I C compatible 4. Reference derived from the power supply. serial interface that operates in standard (100 kHz), fast (400 kHz), 2 5. Standard, fast, and high speed mode I C interface. and high speed (3.4 MHz) modes. 6. Designed for very low power consumption. The references for AD5602/AD5612/AD5622 derive from the 7. Power-down capability. When powered down, the DAC power supply inputs to give the widest dynamic output range. Each typically consumes <150 nA at 3 V. device incorporates a power-on reset circuit that ensures the DAC 8. Power-on reset and brownout detection. 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.
