• LINEAR Multiple Output Range 16-Bit DAC Design Made Simple Design Note 337 handbook

  This document describes a simple design for a multiple output range 16-bit DAC. The product is suitable for industrial process control equipment, analytical and scientific instruments, and automatic test equipment. With the new LTC®1592 multiple output range DAC, all standard industrial ranges can be accurately and software-configurably outputted.

• LINEAR An Autoranging True RMS Converter Design Note 339 Philip Karantzalis Jim Mahoney handbook

  This document is about the design note of LTC1966, introduces the features and characteristics of LTC1966

• LINEAR dn340f Data Sheet

  This article introduces a DC/DC converter for driving Lumileds white LEDs from a variety of power sources. The converter combines a traditional voltage feedback loop and a unique current feedback loop to operate as a constant-voltage, constant-current DC/DC converter. No external op amps are required, saving cost and space.

• LINEAR Dual Smart Battery Charger Simplifies Battery Backup for Servers Design Note 342 handbook

  This design note describes a dual smart battery charger for use in server battery backup. The circuit can charge batteries at up to 4A and switch continuously down to zero load currents. The circuit takes advantage of ceramic capacitors’ space saving features without sacrificing circuit performance.

• LINEAR Basic Flashlamp Illumination Circuitry for Cellular Telephones/Cameras Design Note 345 Jim Williams

  This design note presents a simple, compact, and high efficiency LED flashlamp circuit suitable for use in cellular telephones and cameras. The circuit uses the LT ®3468-1 as the main controller.

• LINEAR Precise Gain Without External Resistors Design Note 348 Glen Brisebois handbook

  The LT1991 is a flexible part that can be configured into inverting, noninverting, difference amplifiers, and even buffered attenuators, just by strapping its pins. It provides you with internal precisely matched resistors and feedback capacitors, so you can easily configure it into hundreds of different gain circuits without external components.

• LINEAR Tiny Efficient High Power LED Camera Flash Solutions for Cell Phone Applications Design Note 1009 Keith Szolusha

  This document introduces a high power LED camera flash solution for cell phone applications. The solution uses LED flash lights, which are small and efficient, and can meet the various needs of cell phones for flash lights.

• LINEAR dn349f handbook

  The LT ®1943 is a highly integrated, 4-output regulator designed to power large TFT LCD panels. It employs switching regulators—instead of linear regulators—to minimize power dissipation and accommodate a wide input voltage range. The wide input range, 4.5V to 22V, allows it to accept a variety of power sources, including the commonly used 5V, 12V and 19V AC adapters. The first buck regulator provides a logic voltage with up to 2A of current. The other three switching regulators provide the three bias voltages, AVDD, VON and VOFF, required by LCDs. All four regulators are synchronized to a 1.2MHz internal clock, allowing the use of small, low cost inductors and ceramic capacitors. Since different types of panels may require different bias voltages, all output voltages are adjustable for maximum flexibility. Programmable soft-start capability is included in all outputs to limit inrush current. The LT1943 has a built-in start-up sequence and panel protection feature. The LT1943 is available in a low-profile 28-pin TSSOP package.

• LINEAR dn351f handbook

  The LT6650 is a low power voltage reference with an output voltage range of 0.4V to 18V. It can be used in single supply and low dropout mode, and has a two-resistor programmable output.

• LINEAR 60V 3A Step-Down DC/DC Converter Has Low Dropout 100 A Quiescent Current Design Note 352 handbook

  This document introduces the LT ®3434, 3A monolithic buck switching regulator, which is designed to optimize efficiency over all current and voltage levels, both high and low, while having low quiescent current and low dropout. Micropower bias current and Burst Mode ® operation enable it to consume merely 100µA at zero load and 12V input. The high efficiency bipolar NPN power switch (0.1Ω) provides up to 85% efficiency at a 2A load current. Combined with high duty cycle, the low dropout of the switch maintains a regulated 3.3V output down to 4V input at all load currents.

• LINEAR 2-Phase Boost Converter Delivers 10W from a 3mm × 3mm DFN Package Design Note 354 handbook

  This document introduces the features of the LT3428, a dual phase boost converter that can start up at 1.5V and output 2A at 5V. The converter operates at 2MHz and has very low output ripple and few components.

• LINEAR DN355f handbook

  This document introduces the op amp selection guide for optimum noise performance by Linear Technology, including noise characteristics, thermal noise of resistors, and quantifying resistor noise.

• LINEAR Compact Step-Up Converter Conserves Battery Power Design Note 358 handbook

  The LT ®3464 is an ideal choice for portable devices which require a tiny, efficient and rugged step-up con- verter.

• LINEAR dn359f handbook

  This document introduces a dual DC/DC converter with integrated Schottky diodes, which generates ±40V outputs and consumes only 40µA quiescent current. The converter is suitable for portable devices with high accuracy and wide input and output voltage ranges.
