The accurate internally generated 50µA current source on the ISET pin allows the user to program an output voltage from 0V to 0.5V below VIN. The user can also directly drive ...
LTC6244 High Speed Peak Detector
Aug 1st 2016
Introduction
Peak detectors capture the extrema of the voltage signal at its input. A positive peak detector captures the most positive point of the input signal and a negative peak detector captures the most negative point of the input signal. Ideally the output of the peak detector circuit tracks or follows the input voltage ...
LTC3256 High Efficiency Dual 5V/3.3V Output Power Supply
Jul 29th 2016
The LTC3256 is a wide input range switched capacitor step-down DC/DC converter that produces two regulated outputs: a 5V output via direct connection to the charge pump output, and a 3.3V output via a low dropout (LDO) linear post-regulator. The device provides up to 350mA of total output current. At 12V VIN and maximum load ...
Baseband Design Example for LTC5589/LTC5599 Low-Power IQ Modulator

High Accuracy, μPower, Over-Voltage Detector with Glitch Suppressor Using LTC1541 and LTC6994
May 4th 2016
An overvoltage detector which suppresses glitches is constructed from the LTC®1541 micropower op amp + comparator + voltage reference and LTC6994-1 TimerBlox® delay block/debouncer. In this circuit, the LTC1541 comparator detects power rail overvoltage conditions (including glitches). The built-in op amp inverts this ...
