The DAC7512 is a low-power, single, 12-bit buffered voltageoutput Digital-to-Analog Converter (DAC). Its on-chip precisionoutput amplifier allows rail-to-rail output swing to beachieved. The DAC7512 uses a versaTIle three-wire serialinterface that operates at clock rates up to 30MHz and iscompaTIble with standard SPI™, QSPI™, Microwire™, andDSP interfaces.The reference for the DAC7512 is derived from the powersupply, resulTIng in the widest dynamic output range possible.The DAC7512 incorporates a power-on reset circuit thatensures that the DAC output powers up at 0V and remainsthere unTIl a valid write takes place in the device. TheDAC7512 contains a power-down feature, accessed over theserial interface, that can reduce the current consumption ofthe device to 50nA at 5V.The low power consumption of this part in normal operationmakes it ideally suited to portable battery-operated equipment.The power consumption is 0.7mW at 5V reducing to1μW in power-down mode.The DAC7512 is available in a SOT23-6 package and anMSOP-8 package.
