DIGITAL-TO-ANALOG CONVERTER
DESCRIPTION
The DAC7512 is a low-power, single, 12-bit buffered
voltage output Digital-to-Analog Converter (DAC).
Its on-chip precision output amplifier allows rail-to-
rail output swing to be achieved. The DAC7512 uses
a versatile three-wire serial interface that operates at
clock rates up to 30MHz and is compatible with
standard SPI, QSPI, Microwire and DSP inter-
faces.
The reference for the DAC7512 is derived from the
power supply, resulting in the widest dynamic output
range possible. The DAC7512 incorporates a power-
on-reset circuit that ensures that the DAC output
powers up at zero volts and remains there until a valid
write takes place to the device. The DAC7512 con-
tains a power-down feature, accessed over the serial
interface, that can reduce the current consumption of
the device to 50nA 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 0.7mW
at 5V reducing to 1
W in power-down mode.
The DAC7512 is available in a SOT23-6 package and
an MSOP-8 package.
