Its differential linearity autocalibration feature allows this high resolution, high speed converter to offer outstanding noise and distortion performance, as well as excellent INL and DNL specifications, over the full military temperature range. Autocalibration effectively eliminates DNL drift over temperature. The AD1385 architecture includes a low noise, low distortion track/hold, a three pass digitally corrected subranging ADC, and linearity calibration circuitry. A complete linearity calibration requires only 15 ms. Precision thin-film resistors and a proprietary DAC contribute to the part’s outstanding dynamic and static performance. The AD1385 uses four power supplies, ± 5 V and ± 15 V, and an external 10 MHz clock. Power dissipation is nominally 2.76 W. Two user selectable bipolar inp……
