DAC7513N/250G4 (TEXAS INSTRUMENTS)

The DAC7513N/250G4 is a low-power single 12-bit buffered voltage output Digital-to-Analog Connector (DAC) with 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.
