New name in high-performance op amps
High-performance op amps allow designers to achieve dual objectives of delivering superior amplifier performance and maintaining very low power consumption.
Fairchild Semiconductor has entered 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

Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
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.

MOSFET is ready for high-voltage car batteries
The new FDB06AN08A1 UltraFET trench MOSFET from Fairchild Semiconductor is designed for 42V automotive battery applications requiring full device capability at low gate drive voltages.
"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 triple- and quad-channel FHP3x50 devices were designed to optimise 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/us slew rate for optimal pulse response.
In addition, the devices' 0.07%/0.03deg 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 (0.05uA 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 single-, dual- and quad-channel devices in the FHP3x30 family offer industry-leading 50MHz bandwidth, 110V/us slew rate and 0.008% /0.01deg 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 versus 130MHz), output current (100 versus 75mA) and DC performance (CMRR: 100 versus 88dB) at the lowest power consumption (2.5 versus 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 analogue products to optimise 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 fulfil 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.
