数模转换器- DAC DAC8551-Q1 Automotive 16-Bit, Ultralow-Glitch, Voltage-Output DAC 8-VSSOP -40 to 125
The DAC8551-Q1 and DAC6551-Q1 are small, low-power, voltage-output, 16- and 12-bit digital-to-analog converters DACs qualified for automotive applications. The DACx551-Q1 devices provide good linearity and minimize undesired code-to-code transient voltages. The devices use a versatile 3-wire serial interface that operates at clock rates to 30 MHz and is compatible with standard SPI, QSPI, Microwire, and digital signal-processor DSP interfaces.
The DACx551-Q1 devices require an external reference voltage to set the output range. The devices incorporate a power-on-reset circuit that ensures the DAC output powers up at 0 V and remains there until a valid write to the device takes place. The devices contain a power-down feature, accessed over the serial interface, that reduces the current consumption to 800 nA at 5 V.
The DACx551-Q1 devices power consumption is only 800 µW at 5 V, reducing to less than 4 µW in power-down mode. The DACx551-Q1 devices are available in a VSSOP-8 package.
