产品说明

The DAC856xT, DAC816xT, and DAC756xT devices are low-power, voltage-output, dual-channel, 16-, 14-, and 12-bit digital-to-analog converters (DACs), respectively. These devices include a 2.5-V, 4-ppm/°C internal reference, giving a full-scale output voltage range of 2.5 V or 5V. The internal reference has an initial accuracy of ±5mV and can source or sink up to 20mA at the VREFIN/VREFOUT 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 DACxx62T devices incorporate a power-on-reset circuit that ensures the DAC output powers up and remains at zero scale until a valid code is written to the device, whereas the DACxx63T devices similarly power up at mid-scale. These devices contain a power-down feature that reduces current consumption to typically 550 nA at 5V. The low power consumption, internal reference, and small footprint make these devices ideal for portable, battery-operated equipment.

The DACxx62T devices are drop-in and function-compatible with each other, as are the DACxx63T devices. The entire family is available in VSSOP-10 and WSON-10 packages.
