в—Џ SOT23-8 AND MSOP-8 PACKAGES The DAC7513 is a low-power, single, 12-bit buffered voltage
output Digital-to-Analog Connector (DAC). The on-chip precision output amplifier allows rail-to-rail output swing to be
achieved. The DAC7513 uses a versatile 3-wire serial interface that operates at clock rates up to 30MHz and is compatible with standard SPIв„ў, QSPIв„ў, Microwireв„ў, and DSP interfaces.
The DAC7513 requires an external reference voltage to set
the output range of the DAC, this allows the DAC7513 to be
used in a multiplying mode. The DAC7513 incorporates a
power-on reset circuit which ensures that the DAC output
powers up at 0V and remains there until a valid write takes
place to the device. The DAC7513 contains a power-down
feature, accessed over the serial interface, that reduces the …
