An Improved 12-Bit Multiplying D/A Converter

The DAC1125 Has Less Than ½LSB 4-Quadrant Feedthrough at 40kHz; Pin-Compatible With the Slower, More-Costly DAC-12M

The DAC1125 is a 12-bit multiplying digital-to-analog converter with high analog linearity, low feedthrough, wide bandwidth, and monotonic performance. It accepts analog inputs of either polarity and multiplies them by a digitally-set gain that has 12 bits of unipolar resolution (complementary-binary digital input), or 11 bits-plus-sign of bipolar resolution (offset-binary or 2's-complement coding).
