The DAC81416, DAC71416, and DAC61416 (DACx1416) are a pin-compatible family of 16‑channel, buffered, high-voltage output digital-to-analog converters (DACs) with 16‑bit, 14‑bit, and 12‑bit resolution. The DACx1416 include a low-drift, 2.5‑V internal reference, eliminating the need for an external precision reference in most applications. These devices are specified monotonic and provide high linearity of ±1 LSB INL.
A user-selectable output configuration enables full-scale bipolar output voltages of ±20 V, ±10 V, ±5 V or ±2.5 V, and full-scale unipolar output voltages of 40 V, 20 V, 10 V or 5 V. The full-scale output range for each DAC channel is independently programmable. The integrated DAC output buffers can sink or source up to 25 mA, thus limiting the need for additional operational amplifiers. Each pair of channels can be configured 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 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 1.7 V to 5.5 V.
