The 12-bit DAC61416, 14-bit DAC71416, and 16-bit DAC81416 (DACx1416) are a pin-compatible family of 16‑channel, buffered, high-voltage output digital-to-analog converters (DACs). The DACx1416 include a low-drift, 2.5‑V internal reference that eliminates the need for an external precision reference in most applications. These devices are specified monotonic and provide high linearity of ±1LSB INL.
A user-selectable output configuration enables full-scale bipolar output voltages of ±20V, ±10V, ±5V or ±2.5V, and full-scale unipolar output voltages of 40V, 20V, 10V or 5V. The full-scale output range for each DAC channel is independently programmable. The integrated DAC output buffers sink or source up to 25mA, and thus limit the need for additional operational amplifiers. Each pair of channels are configurable to provide a differential output with offset calibration. The three dedicated A-B toggle pins enable dither signal generation with up to three possible frequencies.
The DACx1416 incorporate a power-on-reset (POR) circuit that connects the DAC outputs to ground at power up. The outputs remain in this state until the device registers are properly configured for operation.
Communication with the DACx1416 is performed through a 4-wire serial interface that supports operation from 1.7V to 5.5V.
