3 Description
The DAC8311 (14-bit) and DAC8411 (16-bit) devices
are low-power, single-channel, voltage output digital-
to-analog converters (DAC). They provide excellent
linearity and minimize undesired code-to-code
transient voltages while offering an easy upgrade
path within a pin-compatible family. All devices use a
versatile, 3-wire serial interface that operates at clock
rates of up to 50 MHz and is compatible with
standard SPI™, QSPI™, Microwire, and digital signal
processor (DSP) interfaces.
All devices use an external power supply as a
reference voltage to set the output range. The
devices incorporate a power-on reset (POR) circuit
that ensures the DAC output powers up at 0 V and
remains there until a valid write to the device occurs.
The DAC8311 and DAC8411 contain a power-down
feature, accessed over the serial interface, that
reduces current consumption of the device to 0.1 μA
at 2 V in power down mode. The low power
consumption of these devices in normal operation
makes it ideally suited for portable, battery-operated
equipment. The power consumption is 0.55 mW at 5
V, reducing to 2.5 μW in power-down mode.
These devices are pin-compatible with the DAC5311,
DAC6311, and DAC7311, offering an easy upgrade
path from 8-, 10-, and 12-bit resolution to 14- and 16-
bit. All devices are available in a small, 6-pin, SC70
package. This package offers a flexible, pin-
compatible, and functionally-compatible drop-in
solution within the family over an extended
temperature range of –40°C to 125°C.
