AD5622:  2.7 V to 5.5 V, <100 µA, 12-Bit nanoDAC® with I2C Compatible Interface, Tiny SC70 Package

Product Details


The AD5602/AD5612/AD5622, members of the nanoDAC® 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 SC70 package. 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 parts are put into power-down mode over the serial interface. The low power consumption of the AD5602/AD5612/AD5622 in normal operation makes it ideally suited to portable battery operated equipment. The power consumption is 0.4 mW at 5 V.

Product Highlights

  1. Available in 6-lead SC70 package.
  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. Brown out detection on power-on-reset.
