GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

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.

1. Available in 6-lead SOT-23 and 8-lead µSOIC 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 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.

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

only powers up 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 µSOIC packages.
