DESCRIPTION

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

1μW in power-down mode.

The DAC7513 is available in an SOT23-8 package and an

MSOP-8 package.
