Fairchild Enters the High-Performance Amplifier Market with Two
Families of 210MHz and 50MHz Bandwidth Devices Based on Its New
BCP6T Technology Fairchild Semiconductor (NYSE:FCS) marks its
entrance into the high-performance amplifier market with five
industry-leading operational amplifiers (op amps). The 210MHz
FHP3x50 and the 50MHz FHP3x30 families allow designers to target a
broad range of high definition (HD) and standard definition (SD)
video applications including set-top boxes, digital TVs and
audio/video amplifiers. These two product families were developed
with Fairchild's new industry leading, proprietary "BCP6T"
technology, an ultra-low capacitance, complementary bipolar process
using silicon-on-insulator (SOI) and deep trench isolation (DTI)
technologies. Fairchild's high-performance op amps allow designers
to achieve their dual objectives of delivering superior amplifier
performance and maintaining very low power consumption. "Fairchild
now leads the high-performance amplifier market with a range of
devices offering designers the best available combination of power
and performance features," said Debbie Brandenburg, Fairchild's
marketing engineer, Signal Conditioning Products. "The FHP3x30
family, for example, provides the lowest available power
consumption combined with 33% higher bandwidth, 33% more output
current and 55% better DC performance than comparable devices. And
our FHP3x50 family offers best-in-class input bias current, which
is an order of magnitude better than any other device in this
performance range. Both families provide 1.5kV charged device model
ESD protection, a real value-add to the customer." The FHP3x50
Family The triple- and quad-channel FHP3x50 devices were designed
to optimize bandwidth in high-speed applications such as HD set-top
boxes. These 210MHz full-power bandwidth (-3dB) op amps exceed HD
video requirements and deliver 1100V/microsecond slew rate for
optimal pulse response. In addition, the devices' 0.07%/0.03 degree
differential gain/phase error improves video quality. The devices
in this family achieve optimal AC performance with a gain flatness
of 0.1dB (50MHz), enabling them to maintain consistent gain over
the entire passband of high-definition video signals. DC accuracy
is also improved due to their industry-leading (0.05 microamps
typical) input bias-current, which allows for more precise
output-voltage levels and minimal droop in AC-coupled applications.
Both devices in Fairchild's 210MHz family operate with just 3.6mA
of supply current per amplifier, with the triple-channel device
offering a disable feature to prevent additional power consumption.
Energy-saving features like these, combined with an excellent
output current rating (+/-55mA), make these devices ideal for
driving multiple video loads. The FHP3x50 products are also well
suited for use in DTVs, audio/video (A/V) amps and projectors and
DVD recorders. The FHP3x30 Family The single-, dual- and
quad-channel devices in the FHP3x30 family offer industry-leading
50MHz bandwidth, 110V/us slew rate and 0.008%/0.01 degree
differential gain/phase to improve performance and save power in SD
video designs. Targeted applications include SD set-top boxes,
DTVs, CCD imaging systems and industrial imaging systems.
Specifically, the FHP3230 device offers the market's best-available
bandwidth (170 vs. 130MHz), output current (100 vs. 75mA) and DC
performance (CMRR: 100 vs. 88dB) at the lowest power consumption
(2.5 vs. 2.7mA). Like the FHP3x50 series, the three amplifiers in
the FHP3x30 family also provide superior gain flatness (16MHz to
0.1dB) to increase system reliability and simplify designs. These
devices operate with just 2.5mA supply current per amplifier while
providing +/- 100mA output capability to effortlessly support four
video loads. Additional performance features include optimal open
loop gain (AOL), power supply rejection ratio (PSRR), and
common-mode rejection ratio (CMRR) -- all better than 100dB -- for
improved dynamic range and gain accuracy. "The BCP6T process used
to develop these five new products demonstrates Fairchild's
commitment to offering leading-edge analog products to optimize
today's consumer electronics systems," Brandenburg said. "In the
months ahead we will continue to expand our portfolio with
additional amplifier products. Our goal is to further help our
customers fulfill the demands of their highly diverse low-power,
high-performance applications." The FHP series of high-performance
amplifiers are available in lead (Pb)-free packages that meet or
exceed the requirements of the joint IPC/JEDEC standard J-STD-020C
and are compliant with the European Union requirements now in
effect. Price (each, 1000 pcs) -0- *T FHP3230 (Dual, HS, 2.7V-12V)
