DESCRIPTION
The DAC8564 is a low-power, voltage-output,
four-channel, 16-bit digital-to-analog converter (DAC).
The device includes a 2.5V, 2ppm/°C internal
reference (enabled by default), giving a full-scale
output voltage range of 2.5V. The internal reference
has an initial accuracy of 0.004% and can source up
to 20mA at the VREFH/VREFOUT pin. The device is
monotonic, provides very good linearity, and
minimizes undesired code-to-code transient voltages
(glitch). The DAC8564 uses a versatile 3-wire serial
interface that operates at clock rates up to 50MHz.
The interface is compatible with standard SPI,
QSPI, Microwire, and digital signal processor
(DSP) interfaces.
The DAC8564 incorporates a power-on-reset circuit
that ensures the DAC output powers up at zero-scale
and remains there until a valid code is written to the
device. The device contains a power-down feature,
accessed over the serial interface, that reduces the
current consumption of the device to 1.3μA at 5V.
Power consumption is 2.9mW at 3V, reducing to
1.5μW in power-down mode. The low-power
consumption, internal reference, and small footprint
make this device ideal for portable, battery-operated
equipment.
The DAC8564 is drop-in and functionally compatible
with the DAC7564 and DAC8164, and functionally
compatible with the DAC7565, DAC8165, and
DAC8565. All these devices are available in a
TSSOP-16 package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
