(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.
APPLICATIONS
• Portable Equipment
• Automatic Test Equipment
• Industrial Process Control
• Data Acquisition Systems
• Optical Networking
DESCRIPTION
The DAC8830 and DAC8831 are single, 16-bit,
serial-input, voltage-output digital-to-analog
converters (DACs) operating from a single 3-V to 5-V
power supply. These converters provide excellent
linearity, low glitch, low noise, and fast settling over
the specified temperature range of –55°C to 125°C.
The output is unbuffered, which reduces the power
consumption and the error introduced by the buffer.
These parts feature a standard high-speed (clock up
to 50 MHz), 3-V or 5-V SPI serial interface to
communicate with the DSP or microprocessors.
The DAC8830 output is 0 V to V_REF. However, the
DAC8831 provides bipolar mode output (±V_REF)
when working with an external buffer. The DAC8830
and DAC8831 are both reset to zero-code after
power up.
For optimum performance, a set of Kelvin
connections to external reference and analog ground
input are provided on the DAC8831.
The DAC8830 is available in an SO-8 package and
the DAC8831 is available in an SO-14 package. Both
have industry standard pinouts (see Table 3, the
Cross Reference table in the Application Information
section for details).
