The AD5320 is a single, 12-bit buffered voltage out DAC that
operates from a single +2.7 V to +5.5 V supply consuming
115
μ
A at 3 V. Its on-chip precision output amplifier allows
rail-to-rail output swing to be achieved. The AD5320 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 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.
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
μ
W in
power-down mode.
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
μ
SOIC packages.
PRODUCT HIGHLIGHT S
1. Available in 6-lead SOT-23 and 8-lead
μ
SOIC 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/
μ
s.
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.
