Description
The DAC80504, DAC70504, and DAC60504 (DACx0504) are a pin-compatible family of low-power, four-channel, buffered voltage-output, digital-to-analog converters (DACs) with 16-, 14-, and 12-bit resolution. The DACx0504 includes a low drift, 2.5-V internal reference, eliminating the need for an external precision reference in most applications. A user-selectable gain configuration provides full-scale output voltages of 1.25 V (gain = ½), 2.5 V (gain = 1), or 5 V (gain = 2). These devices operate from a single 2.7-V to 5.5-V supply, are specified monotonic, and provide high linearity of ±1 LSB INL.
Communication to the DACx0504 is performed through a 4-wire serial interface that operates at clock rates of up to 50 MHz. The VIO pin enables serial interface operation from 1.7 V to 5.5 V. The DACx0504 flexible interface enables operation with a wide range of industry-standard microprocessors and microcontrollers.
The DACx0504 incorporate a power-on-reset circuit that powers up and maintains the DAC outputs at either zero scale or midscale until a valid code is written to the device. These device consume a low current of 0.7 mA/channel at 5.5 V, making these devices an excellent choice for battery-operated equipment. A per-channel power-down feature reduces the device current consumption to 15 µA.
The DACx0504 is characterized for operation over the temperature range of –40°C to +125°C, and is available in a small, 3-mm × 3-mm QFN package.
