Linear Technology has announced the LT3582, LT3582-5 and LT3582-12 dual channel DC/DC converters which deliver both positive and negative outputs required in many biasing applications such as active matrix OLED (organic light-emitting diode) displays as well as CCD (charge coupled device) applications. The LT3582/-5/-12 offer an I2C interface that can dynamically program output voltages, power sequencing and output voltage ramps as the applicatio...

Linear Technology Corporation has announced a high reliability grade version of the LTC3780, a very high efficiency synchronous buck-boost switching regulator DC/DC controller that operates from input voltages above, below or equal to the output voltage. High power buck-boost circuits typically rely on transformers or two DC/DC converters, one for step-up (boost) and the other for step-down (buck) conversion.

Linear Technology has introduced the LT2940, a power and current monitor for 4V to 80V systems. The LT2940 provides the necessary circuits to accurately measure, monitor and control power in situations where both the current and voltage may vary due to supply voltage uncertainty, component parametric changes, transient conditions or time-varying signals.

Linear Technology Corporation introduces a family of dual and single high IF sampling 14-bit, 170Msps, 210Msps and 250Msps analog-to-digital converters (ADCs) that maintain good SFDR performance at input frequencies up to 900MHz. The LTC2152-14 and LTC2157-14 are single and dual channel simultaneous sampling ADCs, respectively, offering double data rate (DDR) LVDS digital outputs. These ADCs are specifically designed to meet the needs of today's ...

Linear Technology has introduced the LTC2366, a 12-bit successive approximation register (SAR) ADC that outputs data at up to 3Msps in tiny 6- and 8-lead TSOT-23 packages. Operating from a single 2.35V to 3.6V supply, the LTC2366 consumes only 7.2mW at the maximum output rate, a 20% power savings over the nearest competitor. With its tiny footprint and very low power dissipation, the LTC2366 is ideal for a wide variety of portable and space-const...

Linear Technology has introduced a complete family of low-power, precision 16-/14-/12-bit unbuffered voltage output digital-to-analog converters. Both the unipolar LTC2641 and bipolar LTC2642 draw only 120uA of supply current while settling to within 0.5LSB for a full-scale step in only 1us. These voltage output DACs feature a 0.5nV•s glitch impulse, which is key for AC applications such as waveform generation. Low glitch reduces the transient ...

Linear Technology has introduced the LTM4611, a complete switch mode DC/DC µModule point-of-load regulator capable of generating its own 5V N-channel MOSFET gate drive for very efficient voltage conversion from 3.3VIN or less to loads as low as 0.8V at up to 15A.

Linear Technology announced the LTC3880/-1, a dual output high efficiency synchronous step-down DC/DC controller with I2C-based PMBus interface for digital power system management. The device combines best in class analog switching regulator performance with precision mixed signal data conversion for unsurpassed ease of power system design and management, supported by the LTpowerPlay software development system with easy-to-use graphical user int...
