National Semiconductor (www.national.com) has saved a raft of products, spanning its analogue offering, for the show in Munich.
The LM4702 is an audio family which has a high voltage operation, 200V and is described as the first, integrated stereo driver at this voltage for high-power amplifiers. The stereo audio amplifier driver can be used to drive highpower, discrete transistors, or Darlington pairs, in systems, which deliver 25 to 300W/channel. Total harmonic distortion is 0.0006 per cent into an 8¦¸ load. The output power is scaled by changing the supply voltage and corresponding output power transistors. The output transistors can be configured in parallel for higher current and power levels, without changes to the basic driver circuit.
The levels of integration eliminate the requirement to design a discrete amplifier which can reduce the design time considerably. By focusing on the output power stage design which is scaleable for 50W audio visual receivers to 500W amplifiers. The integration also saves board space, as the driver can replace a stereo pair of discrete drivers. By using multiple drivers, they can also be used for multi-channel surround-sound applications.
The monolithic output stage driver is optimised for high supply voltages. The LM4702C targets high-volume applications, for example stereo systems and audio/visual receivers. The LM4702B has a higher voltage
rating of ¡À20 to 100V. It also has tighter specifications for high-end audio, guitar amplifiers, professional audio amplifiers and high-fidelity-powered speakers.
The LM4702A is intended for ultra-high-end consumer and professional audio, with limits tested and guaranteed over voltage and temperature from the same range as the LM4702B. Packaged in a 15lead, TO-220 package, the devices can be delivered in leadfree versions. They are also available in a military 883-compliant, gold-plated TO-3 package.
The company is also introducing a dual, highfidelity audio operational amplifier which is claimed to practically eliminate distortion. The LM4562 amplifier boasts an exceptionally low total harmonic distortion (THD) value of 0.00003 per cent. This is an order of magnitude improvement on industry competitors that are generally 0.0003 per cent THD.
Designed for professional and high-end audio applications, such as audio/visual receivers, preamplifiers and mixers as well as medical imaging and industrial applications. It combines a fast 6MHz, unity gain bandwidth operational amplifier with a proprietary stereo audio power audio.
The device offers an audio dynamic range maximised with an output stage which can swing to within 1V of either power supply voltage when driving 2k¦¸ loads or to within 1.5V when driving 600¦¸ loads. It is unity-gain stable over a wide range of ¡À2.5 to 17V and has an output current capability of 45mA. The input circuitry maintains common-mode and power-supply rejection rates of over 108dB and a typical low input bias current of 10nA.
It is available in a standard SOIC and DIP packages, with lead-free options, samples and evaluation boards.
What is described as the industry's first 14bit, dual, 1GHz input bandwidth ADC with serial low-voltage differential signalling (LVDS) outputs will also be seen at Munich on the National Semiconductor stand.
The ADC14DS105 is made up of 16 12 and 14bit ADCs (eight dual serial LVDS and eight single channel CMOS) which are distinguished by low power consumption, courtesy of the lowpower pipeline architecture in its 0.18¦Ìm CMOS process technology. The bandwidth performance enables noise and distortion performance for 240MHz and higher intermediate frequencies.
The 12bit products in the family can be used in 3G receivers to digitise one or two carriers. The 14bit versions can digitise three or four carriers which require a higher dynamic range. The ADC family eliminates an IF stage, relaxes filtering constraints and permits multi-carrier architecture by virtue of its typical SNR (signal to noise ratio) of 72dB and SFDR (spurious free dynamic range) of 83dB at 240MHz input.
Sample rates are from 65 to 105Msample/sec. LVDS outputs reduce system noise while decreasing the number of I/O pins and traces for signal routing and flexible system partitioning.
The dual ADCs are supplied in lead-free, 60pin leadless lead frame packages (LLPs) and the single versions are in lead-free, 32pin LLPs.
Finally, for power management, the company will be launching two integrated power management units, the LP3906 and LP3905, for mid-range, quad output applications, including low-power FPGAs, microprocessors and DSPs.
The LP3906 has dynamic voltage scaling with 96 per cent conversion efficiency. In this way, it reduces the power consumption of the target device, reducing the system's power budget. Two integrated, 1.5A buck regulators, each with an output range of 0.8 to 3.5V, are integrated with two 300mA linear regulators with an I2C-compatible interface. The device can be used to power an embedded processor, each switching regulator can drive the core and I/O while each low voltage dropout regulator supplies the analogue and peripheral functions. In FPGAs, for example, the dual regulators can power the core and I/O voltages while the dual low dropout regulators power the auxillary voltages for embedded peripherals, such as communications engines.
The LP3906 is available in a 24pin, thermally enhanced LLP, measuring 4 x 5mm. The LP3905 on the other hand is a 14pin thermally enhanced LLP that measures 4 x 4mm. Its buck regulators have a fixed and adjustable output voltage ranging from one to 3.3V with up to 90 per cent efficiency. The buck regulators feature intelligent automatic switching between PWM and PFM modes for efficiency across the entire load. The dual linear regulators have an output voltage range from 1.5 to 3.3V with low dropout voltage and low output voltage noise.
