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 1 µW in power-down mode.
The DAC7513 is available in an SOT23-8 package and an MSOP-8 package.
