в—Џ SOT23-6 AND MSOP-8 PACKAGES 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 SPIв„ў, QSPIв„ў, Microwireв„ў, 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 …
