The LT3029 is a dual, micropower, low noise, low dropout linear regulator. The device operates either with a common input supply or independent input supplies for each channel, over an input voltage range of 1.8V to 20V. Each output supplies up to 500mA of output current with a typical dropout voltage of 300mV. Quiescent current is well controlled in dropout. With an external 10nF bypass capacitor, output noise is only 20?VRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 55?A quiescent current per channel makes it an ideal choice. In shutdown, quiescent current drops to less than 1?A. Shutdown control is independent for each channel, allowing for flexible power management.The LT3029 optimizes stability and transient response with low ESR ceramic output capacitors, requiring a minimum of only 3.3?F. The regulator does not require the addition of ESR, as is common with other regulators.Internal circuitry provides reverse-battery protection, reverse-current protection, current limiting with foldback and thermal shutdown. The device is available as an adjustable output voltage device with a 1.215V reference voltage. The LT3029 is offered in the thermally enhanced 16-lead MSOP and 16-lead, low profile (4mm ? 3mm ? 0.75mm) DFN packages.Applications General Purpose Linear Regulator Battery-Powered Systems Microprocessor Core/Logic Supplies Post Regulator for Switching Supplies Tracking/Sequencing Power Supplies

The LTC2498 is a 16-channel (8-differential) 24-bit No Latency ??? ADC with Easy Drive technology. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances, and rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy. The LTC2498 includes a high accuracy temperature sensor and an integrated oscillator. This device can be configured to measure an external signal (from combinations of 16 analog input channels operating in single ended or differential modes) or its internal temperature sensor. The integrated temperature sensor offers 1/30th ?C resolution and 2?C absolute accuracy. The LTC2498 allows a wide common mode input range (0V to VCC), independent of the reference voltage. Any combination of single-ended or differential inputs can be selected and the first conversion after a new channel is selected is valid. Access to the multiplexer output enables optional external amplifiers to be shared between all analog inputs and auto calibration continuously removes their associated offset and drift.Applications Direct Sensor Digitizer Direct Temperature Measurement Instrumentation Industrial Process Control

The LT3758/LT3758A are wide input range, current mode, DC/DC controllers which are capable of generating either positive or negative output voltages. They can be configured as either a boost, flyback, SEPIC or inverting converter. The LT3758/LT3758A drive a low side external N-channel power MOSFET from an internal regulated 7.2V supply. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages.The operating frequency of LT3758/LT3758A can be set with an external resistor over a 100kHz to 1MHz range, and can be synchronized to an external clock using the SYNC pin. A minimum operating supply voltage of 5.5V, and a low shutdown quiescent current of less than 1?A, make the LT3758/LT3758A ideally suited for batterypowered systems.The LT3758/LT3758A feature soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit. The LT3758A has improved load transient performance compared to the LT3758.APPLICATIONS Automotive Telecom Industrial

DC1414B-B: Demo Board for the LTM4601AHV 12A, 28VIN DC/DC µModule Regulator with PLL, Output Tracking and Margining.

Demonstration Circuit 1419 is a 1.5MHz current mode step-down switching regulator with programmable output current limit featuring the LT3663. The current limit accurately controls the system power dissipation and reduces the size of the power path components. The demo board operates with a 7.5V to 36V (60 transients) input voltage range. The output can be set to 3.3V or 5V using jumper J4, and the current limit can be set to 0.6V, 0.8V, 1V or 1.2V using jumpers J2 and J3.

The LTC6605-7 contains two independent, fully differential amplifiers configured as matched 2nd order lowpass filters. The f?3dB of the filters is adjustable in the range of 6.5MHz to 10MHz.The internal op amps are fully differential, feature very low noise and distortion, and are compatible with 16-bit dynamic range systems. The inputs can accept single ended or differential signals. An input pin is provided for each amplifier to set the common mode level of the differential outputs.Internal laser-trimmed resistors and capacitors determine a precise, very well matched (in gain and phase) 7MHz 2nd order filter response. A single optional external resistor per channel can tailor the frequency response for each amplifier.Three-state BIAS pins determine each amplifier?s power consumption, allowing a choice between shutdown, medium power or full power.The LTC6605-7 is available in a compact 6mm ? 3mm 22-pin leadless DFN package and operates over a ?40?C to 85?C temperature range.Applications WCDMA ADC Driver/Filter Antialiasing Filter Single-Ended to Differential Conversion DAC Smoothing Filter Zero-IF Direct Conversion Receivers
