Linear Technology has announced the LT3497, a dual, full- featured, step-up DC/DC Converter designed to drive up to 12 white LEDs from a Li-Ion input. Its high efficiency, fixed frequency operation ensures uniform LED brightness, low noise and maximum battery life, and the on-chip schottky diodes eliminate both the added cost and space of external diodes. True Color PWM dimming enables dimming ranges of up to 250:1 without any color shift of the ...

Linear Technology has introduced the LT5554, a broadband digitally programmable gain IF amplifier, featuring a 48dBm OIP3 (output 3rd order intercept) at 200MHz. Additionally, the amplifier has very low noise, enabling very high dynamic range performance in wireless communication receivers and signal processing systems.

Linear Technology has introduced the LTM9002, a dual IF/baseband receiver subsystem that includes a high performance dual 14-bit Analog-to-Digital converter (ADC) sampling up to 125Msps, anti-aliasing filters, fixed gain differential ADC drivers and 12-bit, trim Digital-to-Analog converters (DACs).

Linear Technology Corporation introduces a family of dual (LTC2158-14) and single (LTC2153-14) high IF sampling 14-bit, 310Msps analog-to-digital converters (ADCs) designed specifically for wide bandwidth digital predistortion (DPD) linearization applications. Digital predistortion is a closed-loop feedback system that samples the distortion bandwidth at the output of the base station transmitter and adjusts the input signal to cancel the power a...

Linear Technology has announced the LT3506 and LT3506A, dual current mode PWM step-down DC/DC converters with two 2A power switches packaged in a 16-lead 5mm x 4mm DFN package. Each channel is capable of delivering up to 1.6A of output current. Their wide input range of 3.6V to 25V makes them ideal for regulating power from a wide variety of sources, including four cell batteries, 5V and 12V rails, unregulated wall transformers, lead acid batteri...

Linear Technology announces the LT3510, a dual current mode PWM step-down DC/DC converter with two internal 2.5A power switches packaged in a 20-lead TSSOP-20E package.
