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.

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.

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.

LT3640: 35V Input (55V Transient), 2MHz Dual Channel Step-Down Regulator with Power-On Reset & Watchdog Timer
Linear Technology Corporation announces the LT3640, a dual channel, current mode step-down switching regulator with a power-on reset and watchdog timer. Its 4V to 35V input voltage range with 55V transient ride through makes it ideal for load dump and cold crank conditions commonly found in automotive applications. The LT3640 uses a unique dual channel design with a high input voltage (4VIN to 35VIN, 55VIN transient) nonsynchronous channel that delivers 1.1A of output current, combined with a lower input voltage (2.5VIN to 5.5VIN) synchronous channel that provides up to 0.9A of continuous output current. Although the part allows separate inputs for each channel, most applications will use the output of the high voltage channel to power the lower voltage channel, offering dual outputs while optimizing efficiency and switching frequency. For example, using a nominal 12V input and a 2MHz switching frequency, the LT3640 can deliver a 3.3V output at 600mA with 85% efficiency via its high voltage channel and a 1.8V output at 800mA with 87% secondary conversion efficiency via its lower voltage channel.
