Texas Instruments’ digital-to-analog converter DAC8560 is a high-performance, easy-to-use DAC featuring a 2.5V, 2ppm/ºC internal reference with 0.004% initial accuracy. It offers breakthrough performance by keeping output glitch energy under 0.15nV-s. The DAC8560 is a low-power, voltage output, 16-bit DAC that includes a 2.5V, 2ppm/°C internal reference (enabled by default), giving a full-scale output voltage range of 2.5 V. The internal reference has an initial accuracy of 0.02% and can source up to 20 mA at the V_REF pin. The device is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages (glitch). It uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz. And is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces.

The DAC8560 incorporates a power-on-reset circuit that ensures the DAC output powers up at zero-scale and remains there until a valid code is written to the device. Its power-down feature, accessed over the serial interface, reduces the current consumption of the device to 1.2 µA at 5 V.

The low-power consumption, internal reference, and small footprint make this device is suitable for portable, battery-operated equipment. The power consumption is 2.6 mW at 5 V, reducing to 6 µW in power-down mode. The DAC8560 is available in an MSOP-8 package. And is priced at $3.50, in 1000 pieces.
