DALLAS, Jan. 19, 2022 /PRNewswire/ -- Texas
Instruments (TI) (Nasdaq: TXN) today introduced the industry's
widest-bandwidth high-input-impedance (Hi-Z) buffer amplifier,
capable of supporting frequency bandwidths as high as 3 GHz. The
wider bandwidth and high slew rates of the BUF802 enable higher
signal throughput and minimal input settling time. Designers can
leverage this faster throughput to measure higher-frequency signals
more accurately in test and measurement applications including
oscilloscopes, active probes and high-frequency data-acquisition
systems. For more information, see www.ti.com/BUF802-pr.
The bandwidth achieved by the BUF802 was previously only
possible by using application-specific integrated circuits (ASICs)
that can increase system design time, complexity and cost. By
eliminating ASICs, designers who use TI's buffer can get to market
faster while achieving a wide dynamic range at a fraction of the
cost. Begin designing today with the reference design, "Flexible
3.2-GSPS multi-channel AFE reference design for DSOs, radar and 5G
wireless test systems."
Achieve ASIC-level performance with the industry's widest
bandwidth
Previous alternatives to ASIC-based design implementations
required dozens of discrete components such as field-effect
transistors (FETs), protection diodes and transistors. These
discrete, FET-input amplifier-based implementations add to a
design's bill-of-materials (BOM) cost and system complexity and are
unable to deliver the same bandwidth as ASICs, thus limiting the
signal throughput of data-acquisition applications.
The BUF802 provides a single-chip alternative to ASICs or
FET-input amplifier-based implementations by integrating the
features of discrete components while providing 10 times wider
bandwidth than FET-input amplifiers, matching the performance of
custom ASICs. To learn more about the differences between the
BUF802 and discrete implementations, see the technical article,
"Simplify analog front-ends with Hi-Z buffers."
Scale front-end designs from 100 MHz to 3 GHz with the same
BOM
The flexible BUF802 is the industry's first buffer to enable
quiescent current adjustment for a range of bandwidth and signal
swing requirements, from 100 MHz to 3 GHz at 1-V peak to peak
(VPP) and as high as 2 GHz at 2 VPP. This
wide adjustment range for bandwidth and signal swing allows
designers to easily scale their front-end designs across multiple
data-acquisition applications, easing system cost and redesign.
Reduce design complexity with integrated functional
modes
Integrated functional modes allow engineers to use the BUF802 as
a standalone buffer or in a composite loop with a precision
amplifier like the OPA140. As a stand-alone buffer, the BUF802 can
help achieve high input impedance and high slew rates in
applications that can tolerate 100-mV offsets or where the signal
chain is AC-coupled. In a composite loop, the new buffer can
achieve high DC precision and 3-GHz bandwidth in applications
requiring 1 μV/°C maximum offset drift.
Package, availability and pricing
The BUF802 is available for purchase on TI.com in a 3-mm-by-3-mm
16-pin very thin no-lead (VQFN) package, and is priced at
US$1.80 in 1,000-unit quantities. The
BUF802RGTEVM evaluation module is available on TI.com for
US$25. TI offers multiple payment and
shipping options on TI.com.
