DAC8562T Digital-to-Analog Converters

Texas Instruments' DAC8562T device is a low-power, voltage-output, dual-channel, 16-bit DAC. This device 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.

This device is monotonic, providing excellent linearity and minimizing undesired code-to-code transient voltages (glitches). It uses 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 DAC8562T device incorporates 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. This device contains 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 this device ideal for portable, battery-operated equipment.

The DAC8562T device is available in VSSOP-10 and WSON-10 packages.
