The AD5300 is a single, 8-bit buffered voltage-out DAC that operates from a single 2.7 V to 5.5 V supply consuming 115 µA at 3 V. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5300 utilizes a versatile three-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI™, QSPI™, MICROWIRE™and DSP interface standards.The reference for AD5300 is derived from the power supply inputs and thus gives the widest dynamic output range. The part incorporates a power-on-reset circuit that ensures that the DAC output powers up to zero volts and remains there until a valid write takes place to the device. The part contains a power-down feature that reduces the current consumption of the device to 200 nA at 5 V and provides software selectable output loads while in power-down mode. The part is put into power-down mode over the serial interface.The low power consumption of this part in normal operation makes it ideally suited to portable battery operated equipment. The power consumption is 0.7 mW at 5 V reducing to 1 µW in power-down mode.The AD5300 is one of a family of pin-compatible DACs. TheAD5310is the 10-bit version and theAD5320is the 12-bit version.

The AD5305 /AD5315/AD5325are quad 8-, 10-, and 12-bit buffered voltage output DACs in a 10-lead MSOP that operate from a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V. Their on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/μs. A 2-wire serial interface that operates at clock rates up to 400 kHz is used. This interface is SMBus compatible at VDD< 3.6 V. Multiple devices can be placed on the same bus.The references for the four DACs are derived from one reference pin. The outputs of all DACs can be updated simultaneously using the software LDAC function.The parts incorporate a power-on reset circuit, which ensures that the DAC outputs power up to 0 V and remain there until a valid write takes place to the device. There is also a software clear function to reset all input and DAC registers to 0 V. The parts contain a power-down feature that reduces the current consumption of the devices to 200 nA @ 5 V (80 nA @ 3 V).The low power consumption of these parts in normal operation makes them ideally suited for portable battery-operated equipment.
