The AD5546/AD5556 are 16-/14-bit, low power, current output, parallel input D/A converters with 4-quadrant multiplying references.
They operate from a single 2.7 V to 5.5 V supply and have built-in 4-quadrant resistors for resistance matching and temperature tracking.
The feedback resistor simplifies the I-V conversion with an external buffer.
The converters are packaged in compact TSSOP-28 packages with operating temperatures from –40°C to +125°C.
They are suitable for applications such as automatic test equipment, instrumentation, digitally controlled calibration, and digital waveform generation.
The devices have various specifications and electrical characteristics, and proper ESD precautions are recommended to avoid damage.
