DAC removes need for external precision reference in most applications

Texas Instruments DACx1416 DACs are a pin-compatible family of 16-channel, buffered, high-voltage output DACs with 16, 14 and 12-bit resolution. The device includes a low drift, 2.5V internal reference, removing the requirement for an external precision reference in many applications. These devices are defined monotonic and offer high linearity of ±1LSB INL. A user selectable output configuration allows full-scale bipolar output voltages: ±20V, ±10V, ±5V or ±2.5V, and full-scale unipolar output voltages of 40V, 20V, 10V or 5V. The full-scale output range for every individual DAC channel is independently programmable. The integrated DAC output buffers can sink or source up to 25mA, therefore, restricting the demand for further operational amplifiers. Each pair of channels can be configured to give a differential output with offset calibration. The three dedicated A-B toggle pins allow dither signal generation with up to three possible frequencies.
