DACx0508 Digital-to-Analog Converters (DACs)

Texas Instruments' DAC60508, DAC70508, and DAC80508 are 8-channel, SPI, voltage-output DACs with precision internal reference

Image of Texas Instruments' DAC60508 Digital-to-Analog ConverterTexas Instruments' DAC60508, DAC70508, and DAC80508 are pin-compatible, low power, 8-channel, buffered voltage-output, digital-to-analog converters (DACs) with 16-, 14-, and 12-bit resolution, respectively. The DACx0508 includes a 2.5 V, 5 ppm/°C internal reference that eliminates 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 = 1/2), 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.

The communication to the DACx0508 is performed through a serial interface that operates at clock rates up to 50 MHz. The VIO pin enables serial interface operation from 1.7 V to 5.5 V. The DACx0508 flexible interface enables operation with a wide range of industry-standard microprocessors and microcontrollers.

The DACx0508 incorporates 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 devices consume low current of 0.6 mA/channel at 5.5 V making it suitable for battery-operated equipment. A per-channel power-down feature reduces the device current consumption to 15 µA. The DACx0508 is characterized for operation over the temperature range of -40°C to +125°C and is available in small packages.
