DAC7563-Q1 - Dual 12-Bit Ultralow-Glitch Low-Power Buff. Voltage-Output DAC

Updated : 2020-01-09 14:29:27
Description

The DAC756x-Q1, DAC816x-Q1, and DAC856x-Q1 (DACxx6x-Q1) devices are low-power, voltage-output, dual-channel, 12-, 14-, and 16-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 5 V. The internal reference has an initial accuracy of ±5 mV and can source or sink up to 20 mA 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 DACxx62-Q1 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 DACxx63-Q1 devices similarly power up at mid-scale. 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 DACxx62-Q1 devices are drop-in and function-compatible with each device in this family, as are the DACxx63-Q1 devices. The entire family is available in a 10-pin VSSOP-10 (DGS) package.
