GENERAL DESCRIPTION
The AD5546/AD5556 are precision 16-/14-bit, multiplying, low
power, current output, parallel input D/A converters. They
operate from a single 2.7 V to 5.5 V supply with ±10 V multi-
plying references for 4-quadrant outputs. Built-in 4-quadrant
resistors facilitate the resistance matching and temperature
tracking that minimize the number of components needed for
multiquadrant applications. The feedback resistor (R
FB
) simpli-
fies the I-V conversion with an external buffer. The AD5546/
AD5556 are packaged in compact TSSOP-28 packages with
operating temperatures from –40°C to +125°C.
