| | IR’s Automotive DirectFET®2 Power MOSFETs Deliver Exceptional Power Density and Performance | | International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced the AUIRF7739L2 and AUIRF7665S2 automotive DirectFET®2 power MOSFETs that deliver exceptional power density, dual-sided cooling and low parasitic inductance and resistance in a robust, reliable and AEC-Q101 qualified package for automotive applications. | | Leer la noticia completa | 26 de Jan de 2010 - 09:00 PM | |
| Diversity tuner for automotive TV applications provides two tuners in a 7mm x 7mm package | | Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX2135 diversity tuner for ISDB-T and DVB-T automotive applications. This device integrates two high-performance signal paths that operate from a single fractional-N synthesizer. Packaged in a small, 7mm x 7mm TQFN, the MAX2135 provides a compact solution compared to designs that use two separate tuner ICs. Additionally, the device features a very low, 3.8dB (typ) UHF noise figure, and it consumes only 330mW when both signal paths are active and 200mW when only one path is active. Uniquely combining a small footprint with low power consumption and low noise, the MAX2135 is ideal for automotive in-dash navigation and entertainment systems. | | Leer la noticia completa | 26 de Jan de 2010 - 08:58 PM | |
| LT6350: Rail-to-Rail Single-Ended to Differential Amplifier Drives High Speed 16- to 18-bit SAR ADCs | | Linear Technology introduces the LT6350, a 33MHz, low noise, rail-to-rail input and output ADC driver that settles to 16-bits in just 350ns. It is suitable for driving the latest highest performance SAR ADCs such as the LTC2393-16. The LT6350 incorporates two op amps and matched resistors to create a differential output from a single-ended high impedance input. As a result, a differential gain of 2 is achieved with no external feedback resistors, and higher gain can be obtained by using feedback resistors. Each of the two internal op amps achieve a low 1.9nV/Hz input-referred noise density, resulting in a total output-referred noise of just 8.2nV/Hz. The LT6350 enables high performance ADCs to achieve better than 110dB SNR over a 1MHz bandwidth. | | Leer la noticia completa | 26 de Jan de 2010 - 08:57 PM | |
| TI introduces single-chip battery fuel gauge with protection | | Texas Instruments Incorporated (TI) today introduced the industry's smallest, full-featured battery fuel gauge integrated circuit for portable consumer, commercial and industrial applications. The bq3060 turns a battery into a "smart battery" that measures and maintains an accurate record of available capacity, voltage, current, temperature and other critical parameters for lithium-based batteries. The single chip also provides robust battery safety, including authentication, short-circuit and discharge protection. | | Leer la noticia completa | 26 de Jan de 2010 - 08:55 PM | |

| Fully integrated, high-voltage scan drivers minimize panel cost in LCD HDTVs | | Maxim Integrated Products introduces the MAX17120/MAX17121, triple/dual, high-voltage, level-shifting scan drivers for TFT panels with integrated gate logic. These devices minimize panel cost in LCD TVs by integrating all logic required to implement a high-performance scan-driver system. Each scan driver has two channels that switch complementarily. Their outputs swing from +40V to -30V and can swiftly drive capacitive loads. In order to save power, these complementary outputs share the charge of their capacitive load before they change states. These devices are well suited for driving large- (MAX17120) and regular-sized (MAX17121) HDTV LCD panels. | | Leer la noticia completa | 23 de Jan de 2010 - 11:48 AM | |
