DAC7563 Dual-Channel 12-Bit DACs

Texas Instruments' DAC7563 devices are low-power, voltage-output, dual-channel, 12-bit digital-to-analog converters (DACs). These devices include a 2.5 V, 4 ppm/°C internal reference, giving a full-scale output voltage range of 2.5 V or 5 V. The internal reference has an initial accuracy of ±5 mV and can source or sink up to 20 mA at the V_REFIN/V_REFOUT pin.

These devices are monotonic, providing excellent linearity and minimizing undesired code-to-code transient voltages (glitch). They use a versatile three-wire serial interface that operates at clock rates up to 50 MHz. The interface is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces. The DAC7563 devices incorporate a power-on-reset circuit that ensures the DAC output powers up and remains at mid-scale until a valid code is written to the device. These devices contain a power-down feature that reduces current consumption to typically 550 nA at 5 V. The low power consumption, internal reference, and small footprint make these devices ideal for portable, battery-operated equipment.

The DACxx63 devices are drop-in and function-compatible with each other. The entire family is available in MSOP-10 and SON-10 packages.
