GENERAL DESCRIPTION

The AD5320¹is a single, 12-bit buffered voltage out digital-to-

analog converter (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 AD5320 utilizes a versatile 3-wire serial interface that

operates at clock rates up to 30 MHz and is compatible with

standard SPI®, QSPI™, MICROWIRE™ and digital signal

processing (DSP) interface standards.

The AD5320 is one of a family of pin-compatible DACs. The

AD5300 is the 8-bit version and the AD5310 is the 10-bit

version. The AD5300/AD5310/AD5320 are available in 6-lead

SOT-23 packages and 8-lead MSOP packages.

PRODUCT HIGHLIGHTS

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.

The reference for AD5320 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.

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.

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.

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.

6. Power-down capability. When powered down, the DAC

typically consumes 50 nA at 3 V and 200 nA at 5 V.
