The 16-bit DAC81404 and 12-bit DAC61404 (DACx1404) are pin-compatible, quad-channel, buffered, high-voltage-output, digital-to-analog converters (DACs). These devices include a low-drift, 2.5-V internal reference that eliminates the need for an external precision reference in most applications. The devices are specified monotonic and provide high linearity of ±1 LSB INL. Additionally, the devices implement per channel sense pins to eliminate IR drops and sense up to ±12 V of ground bounce.
A user-selectable output configuration enables full-scale bipolar output voltages of ±20 V, ±10 V, and ±5 V; and full-scale unipolar output voltages of 40 V, 20 V, 10 V and 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 15 mA, thus limiting the need for additional operational amplifiers.
The DACx1404 incorporate a power-on-reset circuit that connects the DAC outputs to ground at power up. The outputs remain in this mode until the device is properly configured for operation. These devices include additional reliability features, such as a CRC error check, short-circuit protection, and a thermal alarm.
Communication to the devices is performed through a 4-wire serial interface that supports operation from 1.7 V to 5.5 V.
