The AD5781 is a single 18-bit, unbuffered voltage-output DAC that operates from a bipolar supply of up to 33 V. The AD5781 accepts a positive reference input in the range 5V to VDD – 2.5 V and a negative reference input in the range VSS + 2.5 V to 0 V. The AD5781 offers a relative accuracy specification of ±0.5 LSB max, and operation is guaranteed monotonic with a ±0.5 LSB DNL maximum specification.

The part uses a versatile 3-wire serial interface that operates at clock rates up to 35 MHz and that is compatible with standard SPI®, QSPI, MICROWIRE, and DSP interface standards. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V and in a known output impedance state and remains in this state until a valid write to the device takes place. The part provides an output clamp feature that places the output in a defined load state.

PRODUCT HIGHLIGHTS

  1. True 18-Bit Accuracy.
  2. Wide Power Supply Range of Up to ±16.5 V.
  3. −40°C to +125°C Operating Temperature Range.
  4. Low 7.5 nV/√Hz Noise.
  5. Low 0.05 ppm/°C Temperature Drift.

Features and Benefits

  • Full-featured evaluation board for the AD5781
  • Link options
  • PC control in conjunction with Analog Devices, Inc., system development platform
  • PC software for control

Product Detail

The EVAL-AD5781 is a full-featured evaluation board, designed to allow the user to easily evaluate all features of the AD5781 voltage output, 18-bit DAC. The AD5781 pins are accessible at on-board connectors for external connection. The board can be controlled by two means, via the on-board connector (J6) or via the system development platform connector (J3). The SDP board allows the evaluation board to be controlled through the USB port of a Windows® XP (SP2 or later) or Vista (32-bit) based PC using the AD5781 evaluation software.
