DAC8501 pdf datasheet(16 位串行输入

The DAC8501 is a low-power, single, 16-bit buffered voltage
output Digital-to-Analog Converter (DAC) optimized for multiplying
operation. Its on-chip precision output amplifier allows
rail-to-rail output swing to be achieved. The DAC8501 uses a
versatile 3-wire serial interface that operates at clock rates up
to 30MHz and is compatible with standard SPI™, QSPI™,
Microwire™, and Digital Signal Processor (DSP) interfaces.
The DAC8501 requires an external reference voltage to set
the output range of the DAC. The DAC8501 incorporates a
power-on reset circuit that ensures that the DAC output
powers up at 0V and remains there until a valid write takes
place to the device. The DAC8501 contains a power-down
feature, accessed over the serial interface, that reduces the
current consumption of the device to 200nA at 5V.
The low-power consumption of this part in normal operation
makes it ideally suited to portable battery-operated equipment.
The power consumption is 1.2mW at 5V reducing to
1μW in power-down mode.
The DAC8501 is available in an MSOP-8 package.
