AD5310:  2.7 V to 5.5 V, 140 µA, Rail-to-Rail Voltage Output 10-Bit DAC in a SOT-23

Product Details


The AD5310 is a single, 10-bit, buffered voltage output DAC that operates from a single 2.7 V to 5.5 V supply, consuming 115 μA at 3 V. Its on-chip precision output amplifier allows rail-to-rail output swing. The AD5310 utilizes a versatile 3-wire serial interface that operates at clock rates of up to 30 MHz and is compatible with standard SPI™, QSPI™, MICROWIRE®, and DSP interface standards.

The reference for AD5310 is derived from the power supply inputs and, therefore, provides the widest dynamic output range. The part incorporates a power-on reset circuit that ensures that 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, which reduces the current consumption of the device to 200 nA at 5 V and provides software-selectable output loads while in power-down mode. The part is put into power-down mode over the serial interface.

The low power consumption of this part in normal operation makes it ideally suited for portable, battery-operated equipment. The power consumption is 0.7 mW at 5 V, reducing to 1 μW in power-down mode.

The AD5310 is one of a family of pin-compatible DACs. The AD5300 is the 8-bit version, and the AD5320 is the 12-bit version. The AD5300/AD5310/AD5320 are available in 6-lead SOT-23 packages and 8-lead μSOIC packages.

Product Highlights

  1. Available in 6-lead SOT-23 and 8-lead μSOIC packages.
  2. Low power, single supply operation. This part operates from a single 2.7 V to 5.5 V supply and typically consumes 0.35 mW at 3 V and 0.7 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 slew rate of 1 V/μs.
  4. Reference derived from the power supply.
  5. High speed serial interface with clock speeds up to 30 MHz. Designed for very low power consumption. The interface only powers up during a write cycle.
  6. Power-down capability. When powered down, the DAC typically consumes 50 nA at 3 V and 200 nA at 5 V.
