DESCRIPTION
The DAC8165 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 DAC8165 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 DAC8165 incorporates a power-on-reset circuit
that ensures the DAC output powers up at either
zero-scale or mid-scale 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 equipment.
The DAC8165 is drop-in and functionally compatible
with the DAC7565 and DAC8565, and functionally
compatible with the DAC7564, DAC8164 and
DAC8564. 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.
