DESCRIPTION
The DAC7512 is a low-power, single, 12-bit buffered voltage
output Digital-to-Analog Converter (DAC). Its on-chip preci-
sion 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 interfaces.
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 0V and remains
there until a valid write takes place in the device. The
DAC7512 contains 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 equip-
ment. The power consumption is 0.7mW at 5V reducing to
1W in power-down mode.
The DAC7512 is available in a SOT23-6 package and an
MSOP-8 package.
