GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD5300 is a single, 8-bit buffered voltage output 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 uses a versatile 3-wire  
serial interface that operates at clock rates up to 30 MHz and is  
compatible with standard SPI , QSPI™, MICROWIRE , and  
DSP interface standards.  
1. Available in 6-lead SOT-23 and 8-lead MSOP packages.  
2. Low power, single-supply operation. This part operates from  
a single 2.7 V to 5.5 V supply and typically consumes 0.35 mW  
at 3 V and 0.7 mW at 5 V, making it ideal for battery-  
powered applications.  
®
3. The on-chip output buffer amplifier allows the output of the  
DAC to swing rail-to-rail with a slew rate of 1 V/µs.  
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 0 V 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.  
4. Reference derived from the power supply.  
5. High speed serial interface with clock speeds up to 30 MHz.  
Designed for very low power consumption. The interface  
powers up only during a write cycle.  
6. Power-down capability. When powered down, the DAC  
typically consumes 50 nA at 3 V and 200 nA at 5 V.  
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. The  
AD5310 is the 10-bit version and the AD5320 is the 12-bit  
version. The AD5300/AD5310/AD5320 are available in 6-lead  
SOT-23 packages and 8-lead MSOP packages.
