DAC8565ICPWR

16位，四通道，超低短时脉冲波形干扰，电压输出数位类比转换器具有2.5V ， 2ppm的/ ΣC内部参考 16-Bit, Quad Channel, Ultra-Low Glitch, Voltage Output DIGITAL-TO-ANALOG CONVERTER with 2.5V, 2ppm/∑C Internal Reference

The DAC8565 is a low-power, voltage-output, four-channel, 16-bit digital-to-analog converter DAC. The device includes a 2.5V, 2ppm/°C internal reference enabled by default, giving a full-scale output voltage range of 2.5V. The internal reference has an initial accuracy of 0.004% and can source up to 20mA at the VREFH/VREFOUT pin. The device is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages glitch. The DAC8565 use a versatile 3-wire serial interface that operates at clock rates up to 50MHz. It is compatible with standard SPI™, QSPI™, Microwire™, and digital signal processor DSP interfaces.

The DAC8565 incorporates a power-on-reset circuit that ensures the DAC output powers up at either zero-scale or midscale until a valid code is written to the device. The device contains a power-down feature, accessed over the serial interface, that reduces the current consumption of the device to 1.3µA at 5V. The low power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment. The power consumption is 2.9mW at 3V, reducing to 1.5µW in power-down mode.

The DAC8565 is drop-in and functionally compatible with the DAC7564 and DAC8164, and functionally compatible with the DAC7565, DAC8165, and DAC8564. All these devices are available in a TSSOP-16 package.
