FEATURES
DESCRIPTION
The
DAC8564
is
a
low-power,
voltage-output,
234
Relative Accuracy: 4LSB
four-channel, 16-bit digital-to-analog converter (DAC).
Glitch Energy: 0.15nV-s
The
device
includes
a
2.5V,
2ppm/
°C
internal
Internal Reference:
reference (enabled by default), giving a full-scale
output voltage range of 2.5V. The internal reference
– 2.5V Reference Voltage (enabled by default)
has an initial accuracy of 0.004% and can source up
– 0.004% Initial Accuracy (typ)
to 20mA at the VREFH/VREFOUT pin. The device is
– 2ppm/°C Temperature Drift (typ)
monotonic,
provides
very
good
linearity,
and
minimizes undesired code-to-code transient voltages
– 5ppm/°C Temperature Drift (max)
(glitch). The DAC8564 uses a versatile 3-wire serial
– 20mA Sink/Source Capability
interface that operates at clock rates up to 50MHz.
Power-On Reset to Zero-Scale
The interface is compatible with standard SPI
,
QSPI
, Microwire, and digital signal processor
Ultra-Low Power Operation: 1mA at 5V
(DSP) interfaces.
Wide Power Supply Range: +2.7V to +5.5V
The DAC8564 incorporates a power-on-reset circuit
16-Bit Monotonic Over Temperature Range
that ensures the DAC output powers up at zero-scale
Settling Time: 10
μs to ±0.003% Full-Scale
and remains there until a valid code is written to the
Range (FSR)
device. The device contains a power-down feature,
Low-Power Serial Interface with
accessed over the serial interface, that reduces the
Schmitt-Triggered Inputs: Up to 50MHz
current consumption of the device to 1.3
μA at 5V.
Power consumption is 2.9mW at 3V, reducing to
On-Chip Output Buffer Amplifier with
1.5
μW
in
power-down
mode.
The
low-power
Rail-to-Rail Operation
consumption, internal reference, and small footprint
1.8V to 5.5V Logic Compatibility
make this device ideal for portable, battery-operated
Temperature Range:
–40°C to +105°C
equipment.
The DAC8564 is drop-in and functionally compatible
APPLICATIONS
with the DAC7564 and DAC8164, and functionally
