Overview

The DAC81408, DAC71408, and DAC61408 (DACx1408) are an 8-channel buffered high-voltage output digital-to-analog converter (DAC) product series with pin compatibility and 16/14/12-bit resolution. The DACx1408 includes a low-drift 2.5V internal voltage reference, eliminating the need for an external precision reference in most applications. These devices are monotonic and offer high linearity of ±1 LSB INL. Users can choose the output configuration, including full-scale bipolar output voltages of ±20V, ±10V, ±5V, or ±2.5V and full-scale unipolar output voltages of 40V, 20V, 10V, or 5V. Moreover, the full-scale output voltage of each DAC channel can be individually programmed and controlled. The integrated DAC output buffer can sink or source up to 25mA, reducing the need for additional operational amplifiers. Each channel pair can be configured to provide a differentially output with offset calibration. Up to three frequencies of dither signals can be generated through three dedicated A - B switching pins. The DACx1408 includes a power-on reset circuit that connects the DAC outputs to ground when power is applied. The outputs will remain in this state until the device registers are properly configured for operation. Communication with the DACx1408 is via a 4-wire serial interface that supports an operating voltage of 1.7V to 5.5V.
