AD5547:  DUAL CURRENT OUTPUT, PARALLEL INPUT, 16-BIT MULTIPLYING DACS WITH 4-QUADRANT RESISTORS

Product Description

The AD5547/AD5557 are dual precision, 16-/14-bit, multiplying, low power, current-output, parallel input, digital- to-analog converters. They are designed to operate from single +5 V supply with ±10 V multiplying references for 4-quadrant outputs with up to 4 MHz bandwidth.

The built-in 4-quadrant resistors facilitate resistance matching and temperature tracking, which minimize the numbers of components needed for multiquadrant applications. In addition, the feedback resistor (RFB) simplifies the I-V conversion with an external buffer.

The AD5547/AD5557 are available in a compact TSSOP-38 package and operate at the extended automotive temperature range of –40°C to +125°C.

    Model
    The model number is a specific version of a generic that can be purchased or sampled.

    Status
    Status indicates the current lifecycle of the product. This can be one of 4 stages:
    • Pre-Release: The model has not been released to general production, but samples may be available.
    • Production: The model is currently being produced, and generally available for purchase and sampling.
    • Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
    • Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).
    Package Description
    The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
