The DAC8164 is a low-power, voltage-output,
four-channel, 14-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 DAC8164 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
The DAC8164 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 2.6mW at 3V, reducing to
1.4μW in power-down mode. The low power
consumption, internal reference, and small footprint
make this device ideal for portable, battery-operated
The DAC8164 is drop-in and functionally compatible
with the DAC7564 and DAC8564, and functionally
compatible with the DAC7565, DAC8165 and
DAC8565. All these devices are available in a
