DESCRIPTION
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 SPI™, QSPI™, Microwire™, 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
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 0.5mW at 5V reducing to
1μW in power-down mode.
The DAC7513 is available in an SOT23-8 package and an
MSOP-8 package.
