Product Details

The AD5602/AD5612/AD5622, members of the _nano_DAC® family, are single 8-/10-/12-bit buffered voltage-out DACs that operates 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 part contains 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. This part operates 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.
